Bentley Systems Inc., the leading company dedicated to providing comprehensive software solutions for sustaining infrastructure, has released the V8i (SELECTSeries 6) 20.07.11.33 version of STAAD.Pro - allows structural engineers to analyze and design virtually any type of structure through its flexible modeling environment, advanced features and fluent data collaboration.
This new release has been designed around enhancing the user experience of our leading general analysis and design application and still continue to expand on the technical capabilities that are the basis of the programs continuing popularity.
The following outlines some of the key developments that have been introduced with this goal in mind.
New STAAD Editor
The Editor in STAAD.Pro has been a mainstay of the STAAD.Pro modelling environment, providing a parallel method for defining and tweaking the data file in order to ensure the data matches each user’s specific needs. This has a basic set of capabilities for colour coding the text to help identify comments and key words.
With SS6 we have providing a far more comprehensive new editor which now provides the following:
- Outline View, gives quick access to key features in the data structure
- IntelliSense, commands are more than colour codes, but as you type, a knowledge of the data structure means you are given assistance in completing the command
- Text Blocking and bookmarking, allows large chunks of the file to be hidden to allow quicker navigation through the data.
- Database Link, gives direct access to the profile databases so that the correct names of profiles can be selected.
- Add repetitive command blocks using code snippets
- Context sensitive help, means that you can quickly investigate requirements of commands simply by clicking F1.
New Building Planner Mode
With the popularity of STAAD.Pro as the analysis tool for the design of so many concrete buildings in India where STAAD Planwin is used for modelling and RCDC used for the design, we have taken this process and built it directly into STAAD.Pro. This allows buildings to be quickly defined in a new modelling mode, using a set of regular plans that are constructed into a building form, analysed and the key concrete components then designed and detailed using RCDC.
Note that currently this is following the design requirements to the IS456 design code.
New Mode Bar
With the addition of the new Building Planner Mode, it was clear that we need to add clarity to the Mode Bar used to identify the different key segments of the programme. The change is subtle, but provides extra clarity. The Modes have been re-ordered into groups to better reflect recognised workflows and using colour to help identify similar capabilities
We have continued to add more design capabilities for both steel and concrete modules and enhance some of the others currently in use to provide greater scope:
- CAN CSA S16-14. This new steel design capability has been added to the Canadian CSA specifications
- SANS 10162-1:2011. Design to the South African steel code of practice for the structural use of steel, part 1. Limit states design of hot rolled steelwork.
- AISC 360. Both versions of the US steel code, 2005 and 2010 have been enhanced to report the designs in metric as well as imperial units and now supports the design of web tapered sections.
- AISC 341. The seismic provisions of this code can be added to the checks performed during designs to the AISC 360 code, accounting for the seismic classification, flexural strength based on frame type, and bracing requirements.
- ACI 318-11. Now supports the 2011 version of this code in the batch processing module. (Inclusion of this in the Concrete Design Mode will follow later)
- AIJ Steel Design codes have been updated to support the specific requirements for the Japanese designers who sometimes need to consider design of the Von Mises stresses without inclusion of torsion stresses. Additionally making the designs more conservative by reducing the effective area for bending.
Eurocode 3 steel design options have been enhanced with support of a much increased set of available steel grades.
- SP 63.13330-12 concrete design to the Russian specification has been added to account for the actualized version of the SP 52 code.
Rebuilt Advanced Analysis Solver
A complete redesign and restructuring of the solution algorithm in the Advanced Analysis solution (Advanced Math Solver) can result in a noticeable performance boost with some of the more complex models used with STAAD.Pro. Also the implementation of a Ritz Vector Method eigen extraction can provide improved dynamic analysis solutions when dealing with large numbers of modes.
Additionally the seismic loading defined in the IBC 2012/ASCE 7 2010 can be assigned as either response spectra or using the equivalent static seismic method.
Fixes and updates
Overall there are almost 200 issues addressed in this new release. 100 of them alone are modifications made in the analysis and design engine that results in giving you the most robust solution to date. To discover the details of every one of these updates refer to the Revision History document that is published with STAAD.Pro in the ReadMe documentation.

(A) Issues addressed in the Analysis/Design engine (100)
A) 01 The calculation to determine the natural torsion for rigid floor
diaphragms with the IS 1893 response spectrum analysis has been corrected. The
effect was being calculated based on values of alpha and delta and about the
centre of rigidity, instead of using factors of (alpha-1) and (beta-1) and
applying the force about the centre of mass. This resulted in over estimating
the torsional forces and thus conservative results.
A) 02 The calculation to determine the natural torsion for rigid floor
diaphragms with the seismic equivalent static method for IS 1893 has been
corrected. The effect was being calculated based on values of alpha and delta
and about the centre of rigidity, instead of using factors of (alpha-1) and
(beta-1) and applying the force about the centre of mass. This resulted in over
estimating the torsional forces and thus conservative results.
A) 03 The IS 1893 seismic load generation has been updated to ensure that the
details of the applied moments about origin due to seismic load are reported
correctly with the presence of rigid diaphragm as the torsion increases the
moment (i.e. MY). Even though this increase in moment is considered in analysis,
this was not considered while reporting the moment MY about origin.
A) 04 The RIGID DIAPHRAGM was corrected in the SS5 release to ensure that when
this was used with a CHANGE command, the additional results were not getting
added correctly. It was subsequently found that under certain circumstances this
correction was not being implemented. This loophole has been corrected.
A) 05 The IS 1893 Response Spectrum analysis specification has been corrected to
include the natural / inherent torsion, generated due to the difference between
CM and CR when dynamic loading is acting along Z direction, which was not
getting added to the original load vector.
A) 06 The Eurocode EN 1993-1-1 steel design routines for calculating the
properties of Class 4 slender, Tee sections has been corrected to ensure that
when multiple such sections are designed the second and subsequent sections used
the appropriate section properties.
A) 07 The ASME NF 3000 2004 code has been updated to correct design of single
angles that have been collated in a group.
A) 08 The AISC 360-05 and AISC 360-10 design codes have been updated to correct
the design of Tee sections ensuring that the value of Cy is calculated
A) 09 The analysis engine has been updated to ensure that when processing a
PMEMBER command which includes a list of non existent members (say 1 TO 1000,
where only 1 and 1000 have actually been defined), only the members that
actually exist will be assigned as part of the PMEMBER. Previously an assignment
list of 1 TO 1000 would represent 1000 segment parts to the PMEMEBER and thus
reported as an error.
A) 10 The Russian steel design modules have been updated to ensure that all
necessary variable are correctly initialised which was causing the design to
A) 11 The analysis has been updated for loading on models with physical members.
If a concentrated force is applied to a PMEMBER specified with an eccentricity
using the D2 parameter, then the eccentricity is included in the analysis.
A) 12 A new test has been introduced in the analysis when analysing a model with
the IS 1893 seismic specification to ensure that the base dimension is not zero
(such as with a simple single line stick model representing a chimney or tower)
and the commands includes the ST parameter. This would result in a divide by
zero error, thus a warning message is reported and the analysis halted.
A) 13 The design of sections to EN 1993-1-1 that have been classified as class 3
and subject to high shear loading have been updated to ensure that the
interaction ratio reported is based on the reduced bending capacity.
A) 14 The Russian steel design modules have been updated for checking when
Mef>30 and a correction introduced for the value of PhiB
A) 15 The principal that when working with dynamic load cases, the mass matrix
is determined from the first dynamic load case. This was inadvertently changed
in the SS5 release and has been reverted to the original philosophy and now an
additional NOTE is included in the output file to indicate the load case from
which the mass matrix has been determined.
A) 16 The provision of RIGID FLOOR DIAPHRAGM was not allowed for when including
compression/tension only support springs, elastic and plate mat foundations. The
addition of nodes for the rigid diaphragm was not being accounted for and would
result in an error in the analysis. This has now been addressed.
A) 17 The BS5950 steel design module has been updated to ensure that composite
members are excluded from the design as these are outside the scope of the
A) 18 The AISC 360 design of tube sections has been updated to ensure that if
the torsional modulus C has not been provided, then it should use C =
2(B-tw)(H-tf)t – 4.5(4-pi)t^3. However the calculation was not including the
wall thickness and hence over estimated the torsional modulus.
A) 19 A new SET option has been added to improve the ability for floor loads to
be defined on inclined surfaces. SET FLOOR ANGLE TOLERANCE (which has a default
of 0.01 degrees) can be used to determine the selection of nodes that will be
included in a FLOOR LOAD command.
A) 20 The ACI 318 concrete design routines for plate elements have been updated
to ensure that only the required steel as per clause 18.104.22.168 is provided.
A) 21 The South African steel design SABS0162-1:1993 output has been updated to
ensure that the header for a TRACK 2 output is only printed once.
A) 22 The ACI 318-11 concrete column design routine has been updated to include
the moment magnification method as outlined in clause 10.10.5
A) 23 The Eurocode design has been updated to include additional SGR parameter
options to cover all 32 steel grades and updated Table 6.1 and 6.2 to define
appropriate buckling curves.
A) 24 The AIJ steel design code has been update to allow a reduced effective
section modulus determined from the flanges only to be used in the design of
wide flange and channel sections.
A) 25 The advanced analysis engine has been completely reformatted with new
routines to provide even faster methods to build and solve the stiffness matrix.
A) 26 The AS 4100 steel design routine has been updated to ensure that tapered
wide flange sections are correctly handled.
A) 27 The track 1 output for an EN 1993-1-1 design has been updated to remove an
unnecessary blank line in the header which will help readability and consistency
with other similar design code headers.
A) 28 The ACI 318-11 concrete design routines have been added. The fundamentals
remain consistent with the previous 318-08 code, but include the addition of the
moment magnification method.
A) 29 The South African standard SANS 0162-1:2011 has been added to STAAD.Pro
for the design of steel members.
A) 30 The Japanese Steel design codes AIJ 2002 and AIJ 2005 have been enhanced
with an additional option on the Von Mises checks to perform the check, but
exclude the torsion stresses which is required by various plant deign
A) 31 The detailed output from an AISC 360-10 design has been updated such that
if the LTB checks are not appropriate to the design, the values of Lb, Lp and Lr
will not be included in the report.
A) 32 The Japanese steel design code AIJ 2002 has been enhanced with an
additional parameter 'YNG' which allows the calculation of fb (eqn 5.8) to
change from fb =8900/(Lb*h/Af)(the default method) to fb=0.433*E/(Lb*h/Af),
where E is taken as the defined value of Young's Modulus as published by the
JSME Eqn SSB-1.10.
A) 33 The AISC 360-10 and AISC 360-05 design codes have been enhanced to support
the design of members with tapered flanges.
A) 34 The seismic load routines have been supplemented with the specification
for IBC 2012 / ASCE 2010.
A) 35 The AISC 360-10 design report has been updated to give the exact equation
for each category of PhiPn.
A) 36 The AISC 360-10 summary output for a TRACK 0 setting has been rationalised
to reduce the amount of unnecessary data printed and making for a more compact
A) 37 The Advanced Analysis engine has been enhanced with an additional method
to extract the dynamic modes using a Ritz Vector method.
A) 38 The AISC 360-05 and AISC 360-10 codes have both been updated to allow the
output reports to be provided in the current length and force units, so can now
be provided in metric and not just English units.
A) 39 The ACI 318 concrete design routines for T shaped beams was modified in
the SS5 release to ensure that if the dimensions of the web and the moment on
the section are such that a suitable area of bars can be determined (i.e.
between Rhomax and Rhomin), then that arrangement is now reported.
A) 40 The AISC 360-05 and AISC 360-10 codes have been updated to support the
design of wide flange sections with cover plates on the top and/or bottom
A) 41 The AISC 360-10 and AISC 360-05 design modules have been enhanced with an
option to include the additional checks as per the corresponding AISC 341
specification 'Seismic Provisions for Structural Buildings'
A) 42 The dynamic analysis routines have been improved when creating the mass
matrix that needs to be saved to disk after completing the eigensolution. With
the V8i SS5 release this would result in the analysis aborting during this
process due to an IO error.
A) 43 The AISC 360-10 TRACK 2 report has been updated to include the torsional
modulus (Ixx) that is being used in the design. Also when wide flange sections
are modified with cover plates on both the top and bottom, the values of
torsional modulus (Ixx) and warping constant (Cw) are modified to enhance the
torsional characteristics that the plates provide.
A) 44 The AISC 360 TRACK 2 output has been revised to indicate the units of the
values being reported in the header with any that are not in those units having
their own unit indicated in that section of the output.
A) 45 The analysis engine has been updated to ensure that if a list command such
as DELETE or INACTIVE MEMBER with a FROM … TO … STEP … is defined such that
(TO-FROM)/STEP is not an integer, then this is reported as an error.
A) 46 The Canadian steel design CSA S16-14 has been added to the range of
available steel design codes.
A) 47 The output from an AISC 360 10 has been updated to correct the value of
Azz that was being reported. However, the value that was being used in the
calculations was correct.
A) 48 This is a note to confirm that AISC 360 clause H3-8, non-HSS sections
subject to combined shear and torsional forces, was corrected in release
20.07.09.31, but not documented in that release. This accounts for members whose
shear centre and centroid do not coincide, resulting in an torsional effect on
A) 49 The design of angle sections to AISC 360-05 and AISC 360-10 has been
improved. The report had previously inverted the values of IY and IZ displayed
and the slenderness calculations had inverted the slenderness factors KY and KZ.
A) 50 The AISC 360 05 and 10 design routines have been enhanced with a new INT
parameter which allows the selection of interaction checks H1-1 and H1-3, the
default INT 0 performs exactly as per earlier releases of STAAD.Pro.
A) 51 The AISC 360-10 design of pipe and HSS round sections has been updated to
better handle forces in orthogonal directions. These forces are now resolved
into a single direction as recommended by the AISC committee and defined by Mr =
sqrt(MY*MY + MZ*MZ) for use in equations such as H3-6.
A) 52 The IBC 2006/2009 response spectrum routines have been enhanced with the
ability to include the torsional effects as done in the Indian IS 1893 code
using the two parameters DEC and ECC to account for the difference between the
centre of mass and the centre of rigidity.
A) 53 The IS 456 concrete design routine has been enhanced with a check on the
value of Young's modulus specified for the concrete which is reported if an
inappropriate value is used. Previously a warning reported excessively high
values >10,000 ksi. Now an additional test checks to prevent using a value of E
A) 54 The analysis engine has been updated to improve the handling of Notional
load cases which under certain conditions would cause the analysis engine to
generate a run-time error.
A) 55 The analysis engine has been updated to include a new and wider set of
properties for models that include the ASSIGN BEAM, COLUMN, CHANNEL or ANGLE
specification to select a profile from the current database where that is
A) 56 The EN 1993-1-1 steel design has corrected the calculation of the warping
constant for channel sections. Previously this could generate negative values,
although the correct magnitude, which when used would result in an incorrect
utilization value which could be non-conservative or report as not a number,
A) 57 The South African steel design code SANS0162-1:1993 has been updated to
correct the design of T section profiles to ensure that the value of MR is
calculated and MRZ as per section 13.5 and 13.6.
A) 58 The South African steel design SABS0162-1:1993 has been updated to ensure
that the effective length factors KY and KZ are used in the determination of the
A) 59 The IS800:2007 design of web tapered members has been improved to ensure
that if the section is subject to tension, the compression capacity is still
calculated and reported correctly.
A) 60 The IS800:2007 steel design has been improved for members defined as truss
members and web tapered where previously the slenderness ratio was reported as
0.0, this is now calculated and reported correctly.
A) 61 The IS800:2007 design of UPT sections has been improved taking into
account the area specified in AX rather than determining the value from the
A) 62 The SNiP 2.23-81 Russian steel design code has been updated to ensure that
the units of yield stress are correctly taken into account.
A) 63 The AISC 360 design routines have been modified to improve the design of
Tee profiles to check for the condition of Iyc/Iy. For sections for which Iyc/Iy
is between 0.1 and 0.9, then their interaction will be determined from clause H2
rather than H1.
A) 64 The Russian steel design code SNiP 2.23-81 has been updated to ensure that
the stability check is not performed where it has a relative eccentricity >20
(i.e. mef > 20).
A) 65 The AISC 360 steel design modules have been enhanced with the
implementation of clause E5, compression capacity of single angles. This
calculates the slenderness from equations 16.1-35 and 16.1-36, rather than
directly from K, L and r.
A) 66 The AISC 360 steel design modules have been modified to ensure that clause
E4 is only used where b/t > 20.
A) 67 The design of steel profiles to the older Russian steel SNiP II-23-81 has
been revised to be initialised by the command CODE RUSSIAN 1990 and the output
heading revised to report 1990 rather than 1998.
A) 68 The Canadian steel design S16-09 has been updated with an improved
algorithm to increase the speed the design process.
A) 69 The Indian steel design IS 800:2007 has been updated with an improved
algorithm to increase the speed the design process.
A) 70 The value of Ix used for a tapered I section for an Australian steel
design AS4100 is now calculated and reported. Previously this was set as 0.0 and
thus resulted in a design ratio of infinity.
A) 71 Designs using the following codes:- AISC 360-10, AISC 360-05, IS800:2007,
Canadian S16-09 and Canadian S16-14 now support the use of ENVELOPE definitions
to determine load cases which will be used for serviceability checks and which
will be used for strength checks when performing member designs. E.g.
201 to 210 ENVELOPE 1 TYPE STRENGTH
101 to 110 ENVELOPE 2 TYPE SERVICEABILITY
END DEFINE ENVELOPE
LOAD LIST ENV 1 2
Will perform a design for load cases 101 to 210 and 201 to 210 where load cases
101 to 110 will be considered for the strength checks and load cases and 201 to
210 will be used for serviceability checks.
A) 72 The old Eurocode concrete design based on the draft for development
publication has been removed from the analysis engine. The current Eurocode 2
EN1992-1-1 design should be performed from the Concrete Mode.
A) 73 The AISC 360 steel design modules have been updated to ensure that for
fabricated sections (i.e. STP 2), the design includes the check for clauses E7-7
A) 74 The old Eurocode 3 Draft for Development design code has been archived as
all designs should adopt the current EN1993-1-1 methods.
A) 75 The analysis engine has been updated to correct the section forces
reported on members that have been loaded with a combination case of static and
response spectrum cases. Also when using the command to create a combination of
an earlier defined combination which was of an ABS or SRSS type.
A) 76 The analysis engine has been updated to support the assignment of a time
history forcing function to a node group definition which previously would cause
the analysis engine to crash.
A) 77 The one way floor loading command has been updated to ensure that it is
included in a Reference Load Case, if the option INLCLINED is included, that
option is accounted for in the load distribution.
A) 78 The Russian steel design code SP16 has been updated to ensure that the
values of Mef and thus Phi_e are correctly calculated for all members in a
design collection. Previously whilst the first member in the design would be
correctly calculated, the second and subsequent members may not be correct.
A) 79 The Eurocode 3 steel design EN 1993-1-1 has been updated to ensure that it
does not crash when set to using the French National Annex, NA4.
A) 80 The Russian steel design SP 16 has been updated to correct the design of
double angle profiles to ensure that the correct area of the composite profile
is used and correcting the the values of Hef and Bef which resulted in incorrect
values for Lamda_UW.
A) 81 A new CB parameter has been added to the Canadian steel design modules
S16-09 and S16-14 to allow a user specified value of Omega2 as was supported in
the earlier S16-01 design code.
A) 82 (The IS 800:2007 LSD and WSD have been updated to ensure that the design
of tapered wide flange sections do not include the section classification limit
as a design criteria which could result in a conservative over estimate of the
A) 83 The Russian steel design codes have been updated to manage better the
assignment of steel grades defined with SGR and MAIN parameters. If an
inappropriate assignment is made such as a rolled steel grade assigned to a
hollow profile, the design for that section is terminated.
A) 84 The detail output of the Russian steel design code SP16.13330 has been
updated to clarify the eqn previously listed as 116 is in fact 117 (which is
used in eqn 116 and the result reported in clause 9.2.9.
A) 85 The AISC 360-05 and 360-10 Unified design codes have been updated to
correct the designs performed on models specified with the SET Z UP option in
which previously the parameters such as K and L were being assigned to the wrong
A) 86 The AISC 360-05 and AISC 360-10 design modules have been updated to
include the parameter WTYP. This is used to indicate the method of fabrication
of an HSS profile.
A) 87 The AISC 360-10 torsion design has been modified such that at this time
TRACK 3 is not supported and a TRACK 2 report will be generated instead.
A) 88 The AISC ASD, 9th Edition has been updated to correct a recently
introduced issue that resulted in the values of CY and CZ for channels and tees
were not getting updated for the second and subsequent members in a group
A) 89 The AISC 360-05 and AISC 360-10 design codes have been updated to include
the LEG parameter which is used to indicate which leg of an angle profile has
been fixed in order to determine which radius of gyration should be used for the
A) 90 The AISC 360-05 and AISC 360-10 design code have been updated to ensure
that the moments reported in the output for an angle profile design were for the
correct axes. Note however that the design itself used the moments about the
A) 91 The Norsok steel member design routine has been updated to ensure that
where the critical design ratio is as a result of Eq. 6.44, this reference is
displayed. Previously, some members could report the reference as Eq. 6.15 which
is simply one of the parts that determine the final ratio. Note however, that
the ratio reported was correct.
A) 92 The output for IBC 2006 and IBC 2012 seismic definitions has been updated
to ensure that the value of CT reported in the output file as per the current
A) 93 In STAAD.Pro V8i SS5 20.07.10.64 a modification was added that attempted
to assist in the analysis of models with warped plates (see A)78 of that
Revision History document). The analysis would modify the stiffness of the
warped plates in order to account for the warped nature of the plate. This
modification has been removed so that the behaviour of STAAD.Pro will be as for
earlier builds of STAAD.Pro. It is highly recommended that models with quad
plates should be checked carefully for any warped plates and make use of the SET
PLATE FLATNESS TOLERANCE command.
A) 94 The AISC 360 design code routines have been further optimised to improve
memory utilization which on some larger models would cause the design cease.
A) 95 The wind loading defined with a Russian SNiP 2011 setting was failing to
create any loading on some asymmetric building frames. Note that this uses a
combined effect of the static force from the wind and dynamic effects of the
structure, hence can result in asymmetric load and forces applied to a
symmetrical structure. Also at this time a statics check will be reported, but
this does not apply and will be removed in a future release.
A) 96 STAAD.Pro does not support multiple time history or ground motion load
cases in a single run, but it is possible to have a case which is re analysed
after a change such as when section profiles have been modified after a design.
Whilst this was possible for time history cases, it was being prevented if the
re analysed case included ground motion. This restriction has now been removed.
A) 97 A new Russian concrete design module has been added to allow design of
concrete members to the Russian design code SP 63.13330.2012. This code
supersedes the SP 52 design code that is currently available in the Concrete
A) 98 The error message reported by the analysis engine has been updated to
clarify the nature of the problem when the required code is not included in the
CHECK SOFT STORY (CODE) command as defined in the Technical Reference manual
section 5.28.2 Floor Diaphragm.
A) 99 The output that is reported using a PRINT SECTION FORCE command has been
updated to include the axial forces at the section locations.
A) 100 The processing of the IS1893 response spectrum command has been updated
to support the ABS combination method which previously would have caused an
error the analysis to abort.
(B) Issues addressed in the Pre-Processing Mode (29)
B) 01 A new Japanese steel design database has been added to support all the H
sections defined in the AIJ 2014 publication.
B) 02 The toolbars have been updated to ensure that the status of their
visibility is recorded and that they are displayed with the same status when the
program is relaunched. So if a toolbar is turned off in one session, the next
time the program is launched, the toolbar remains turned off, but can be turned
on again from the menu item View>Toolbars...
B) 03 The Output Viewer has been updated to ensure that if any output file
(*.ANL) is double clicked, it opens and is displayed in the viewer. Previously
this would cause the Viewer to crash.
B) 04 The old Japanese steel database of H sections has been updated. The IZ
value of the H346x174x6 profile has been corrected.
B) 05 The GUI has been updated to process the command line DEFINE IS 1893 LOAD
which includes the parameter PART4, but where a space has been incorrectly
introduced between PART and 4. This will be reported as an error rather than
simply removed when the file is re-saved.
B) 06 The menu in the Modelling Mode that displays section properties for a
selected country has been updated for the European steel database which
previously was not including the rectangular, square and circular hollow section
B) 07 The GUI has been updated to process PRINT SECTION FORCE commands that have
list defined after the command as meaning ALL, i.e. this is treated as PRINT
SECTION FORCE ALL rather than identifying this as an error.
B) 08 Sample STD files for the Verification Examples as outlined in section
"Steel-AISC LRFD" have been added to the installation.
B) 09 The US steel database has been updated to the publication from the AISC
v14.1. Note however that the publication does not include B Shapes or Tubes, but
these have been retained for information. Also the additional shapes, Heavy
W-Shapes Large L Shapes and Jumbo HSS have been added.
B) 10 The Modes bar and menu has been updated to help in navigation.
B) 11 The Properties dialog box has been updated to improve the editing of user
defined pipe and tube sections. If a profile has been defined with specified OD

properties of an angle arranged in a star formation is reported correctly.
B) 17 The GUI has been updated to ensure that if an older Russian SNiP seismic
load definition is created and the option 'SAVE' is selected, then if the
seismic definition is changed to the newer Russian code, the SAVE option is
removed as this is not available in the newer code. This would have been
reported as an error when the file is next read back.
B) 18 The member query dialog has been updated to display the value of effective
concrete width defined for wide flanged members including a composite action as
given in the CW parameter.
B) 19 The GUI has been updated to ensure that if the command to report the

localised with future language packs.
B) 22 The Eurocode combination generator has been updated with a method option
which allows the combinations to be created as repeat loads in a new set of
primary load cases or alternatively as before in a set of combination cases.
B) 23 The response spectrum loading definition in the loading dialog has been
updated for the IBC 2006/ASCE 7-05 definition to ensure that changing the site
class does not revert the values of Fa and Fv back to their default values.
B) 24 The database of Jindal steel profiles has been updated to reflect their
current section range for ISMC and UC shapes.
B) 25 The text editor has been completely re-designed and enhanced with

edited, that setting is correctly assigned to the input file.
B) 30 The GUI has been updated to handle the assignment of FLOOR Loads to a
group that has not been defined and report this as an error when opening a file
with such a command. Previously, it would remove that command and any subsequent
data if the file is re-saved.
(C) Issued Addressed in the Post-Processing Mode (09)
C) 01 The Unity Check table in the Post Processing> Beam>Unity Check Page has
been updated to allow the data to be copied to the clipboard and pasted into

units. Also a more generic method for calculation for Ec is now used based on
the method defined in the AISC Design Guide 11.
C) 07 The Indian steel design IS 800-2007 has been updated to ensure that if
slenderness option has been turned off with the MAIN parameter, then it is not
displayed in the Steel Design page of the member query dialog.
C) 08 The Member Query dialog has been updated to correct the displayed self
weight results for members that have been assigned with a fire proofing system.
Previously this would evaluate the applied loading based on the CFP
specification instad of BFP, hence the incorrect diagrams. However, note that
the diagrams and results elsewhere in the main application were unaffected by
C) 09 Post processing of prismatic sections where, on top of the basic
dimensions YD and/or ZD, the section properties have been defined in the input
file, have been updated for reporting the stresses in the Beam>Stresses page.

(E) Issues Addressed in the Concrete Design Mode (06)
E) 01 The concrete column design to the Russian SP52 design code has been
updated to ensure that if the column is subjected to a tensile load case, then
the design will cease with a message that columns are currently not designed for
E) 02 The detail report for a Eurocode 2 beam design shear details. The Max
allowable transverse spacing between shear legs would show no value and the
largest actual transverse spacing between shear legs would display some enormous
value. The actual design status would however be reported correctly as OK or
E) 03 The Eurocode 2 EN1992-1-1 calculation of minimum reinforcement has been
updated to ensure that...
E) 04 The design of beams to EN1992-1-1 has been updated to ensure that where
the beam is subject to only sagging moments (such as a simply supported beam),
then the minimum (hogging) moment that should be considered in the span is not
extended to the full length of the beam. Additionally the reported minimum area
of tension reinforcement and shear links has been corrected.
E) 05 The Canadian Concrete code CSA A23.3-10 has been updated to correct the
minimum prescriptive requirements for transverse spiral reinforcement in
E) 06 The Concrete Design module has been updated to improve the member property
reading routines which caused some models to cause STAAD.Pro to crash when

require configuration files to be hosted away from the application folder.
I) 02 The calculation engine in FreeSketch has been re factored to provide a
more robust solution algorithm to determine the section properties of the
defined profile using the method from the Bentley Structure Property Catalog.
I) 03 The help documentation for Section Wizard and Advanced Mesher have been
updated to the CHM format which is more compatible with current operating
I) 04 The method of calculation of the shear centre in the FreeSketch module has
I) 05 The routine implemented to calculate the plastic modulus values Wplu and
Wplv in FreeSketch which were incorrectly based on the elastic axes have been
corrected to use the equal area axes.
I) 06 The DXF import routine in FreeSketch has been improved such that any curve
or circular lines are subdivided as per the specification in the Preferences

for which it can report the torsional modulus It.
I) 08 The Equal Area axes used to calculate the plastic section properties are
now included in the FreeSketch report. Note that previously these were only
reported in the Section Builder module.
I) 09 The calculations of plastic properties have been completely restructured
and reported correctly about the equal area axes in both FreeSketch and Section
I) 10 The GUI has been updated to include an option to display the analysis log
file (*.log) created during the analysis process and located in the model
folder. This is accessed from the File menu > View > Analysis Log.
I) 11 The legend on the influence surface diagram has been updated to show not
only the percentage but also the actual magnitude of the effect based on the
application of a unit load at each location across the model.
I) 12 The STAAD.foundation module included with STAAD.Pro has been updated to
use XSXML 6 to avoid a known security risk with the earlier versions of XSXML.
I) 13 The CIS/2 module has been enhanced to support the import and export of
pipe sections that are not defined in a published catalogue but instead simply
defined with external and internal diameters. Previously these section
properties would have been omitted from the STP file on export and STAAD.Pro
model on import.
I) 14 The ISM creation routines have been updated to allow models to be created
with alternative unit formats, such as where the regional settings use the comma
as a decimal marker.
I) 15 The STAAD.Pro User Table export from the Section Builder module in Section
Wizard has been modified to set the shear areas to 0.0 rather than simply using
the cross sectional area which was done previously.
I) 16 The values of torsional modulus IX and warping constant HSS that are
exported to a STAAD.Pro User Table have been rewritten to produce more accurate
values for a wider range of profiles where previously the calculations resulted
in negative values for these properties.
I) 17 The export of a profile in Section Builder to a STAAD.Pro User table has
been modified such that the values of shear area are now set to 0.0 as
previously they were set to an un-conservative value of Ax. This needs to be set
to a manually determined value by the user.
I) 18 A new modelling mode 'Building Planner' has been added to STAAD.Pro
specifically to create concrete building models that can be designed with the
RCDC Design application. (Note separate licenses are required to activate the
(J) Issues Addressed in OpenSTAAD (02)
J) 01 A duplicated copy of the OpenSTAAD manual has been removed from the
installation. The relevant copy is retained in the Help folder.
J) 02 Three new OpenSTAAD functions have been added to access the data of the
profile definition of GENERAL USER TABLE sections that include profile points.
GetProfileBoundaryInformation(LONG tableNo,STRING "profile name",LONG
nOuter,LONG nInner). The return value is a BOOLEAN that indicates that the
profile exists and the number of inner and outer boundaries defined. LONG
nPOINTS = Property.GetProfileNoOfPoints(LONG tableNo, STING "Profile name", BOOL
IsInner, LONG nIndex) returns the number of points on a boundary. For the outer
boundary, IsInner should be set to FALSE and nIndex set to 0. For an inner
boundary, then IsInner should be set to 1 and nIndex should be the index number
of the inner boundary. Finally, Property.GetProfileBoundaryPoints(LONG tableNo,
STRING "Profile Name", BOOL IsInner, LONG nIndex, DOUBLE ZP(), DOUBLE YP()) for
the given tableNo, Profile Name and boundary the two array ZP() and YP() are
filled with the ordinates of the profile points.

torsional forces that can be generated.
K) 14 Section 188.8.131.52 Mass Modelling has been updated to clarify possible
effect of including CON member loads on the mass matrix.
K) 15 The technical details of Master/Slave settings have been updated to
clarify that due to the mechanisms used to include master/slave systems, if the
reactions on master nodes are not included in a statics check and can result in
an out of balance report. This can be avoided by adding a short stiff member
from a master node to the support.
K) 16 Details of 4 dynamic functions have been added to the OpenSTAAD manual.

support the methods used in the current Windows operating systems.
K) 20 Sections 5.25 Member Offset Specification and 5.26.2 Specifying Constants
for Members and Elements of the Technical Reference manual have been updated to
clarify that "Local offsets are defined in the local axes prior to rotation when
a BETA angle is used."
(L) Issues Addressed with licensing / security / installation (03)
L) 01 The icons in the License Configuration Panel on the Start Screen have been
updated to ensure that they display the appropriate status if turned off. Whilst
the program behaved correctly, there were times when rather than displaying a
grey icon and unset, the application would show a red icon and a check next to
the item. Restarting the program would display the correct status.
L) 02 The warning that is reported in the output file when the applied vertical
load is less that the self weight has been reformatted to ensure that it fits in
a standard page and does not generate a warning when being printed.
