(A) Analysis/Design Engine (40)
A) 01 The Indian cold formed design code IS 801, Cold-Formed Light Gauge Steel Structural Members in General Building Construction, which was withdrawn from STAAD.Pro in version CE Update 3 due to discovered defects, has been re-enabled with the founds issues addressed.
A) 02 The Indian concrete code IS 13920-2016 Code of Practice for Ductile Detailing of Reinforced Concrete Structures Subjected to Seismic Forces implemented in CE Update 3 has been extended by including the provision given in section 8 Special Confining Reinforcement for beam design.
A) 03 The Indian concrete code IS 13920-2016 has been enhanced with additional logic for both beam and column design with regard to the axial loading. Refer to the help section on IS 13920 for more details.
A) 04 A new provision has been added to assist for the design of concrete structures designed to IS 1893-2016. The method to allow for a reduced section property due to cracking has been extended such that when identified as reductions for IS 1893-2016, then the model will be analysed using the full section properties, except for the load cases with a IS1983-2016 seismic or response spectrum load defined.
A) 05 The design of concrete structures to IS 1893-2016 has been enhanced with the ability to include the irregularity checks including mass irregularity, irregular modes of vibration and torsion irregularity. Note that these checks are available for models that include floor diaphragms.
A) 06 The Track 2 output for the revised implementation of IS 801 Indian Standard Cold-Formed Light Gauge Steel Structural Members in General Building Construction, will ensure that if a is used on a member that includes tensile forces, the details of the tensile force are included in the output.
A) 07 The design routine for IS 801 has been updated to ensure that the details of the elastic modulus are obtained directly from the section database rather than re-calculated.
A) 08 The detail output for the IS 801 cold formed steel design has been redesigned and uses the correct clause reference for the Bi-axial Bending and Bending-Compression checks.
A) 09 The revised implementation of the IS 801 cold formed steel design now includes an operational slenderness check which was not the case in the earlier V8i implementation.
A) 10 The default values for Yield Stress (fy) and Ultimate Tensile Stress (FU) in the IS 801 cold formed steel design module, have been updated such that fy = 3600 kgf/cm^2 (Ref table 2 of IS 801) and fu = 4588 kgf/cm^2 (as the code does not provide a default value)
A) 11 The output for the re-issued IS 801 Indian cold formed steel design has included a modification such that the allowable stresses are reported in Mpa for a Metric model or ksi for a model in English units.
A) 12 The re-issued IS 801 Indian cold formed steel design has included a test to validate the section area provided in the section database. If this is found to be zero, then a value will be determined based on the section dimensions, otherwise the value in the database will be used.
A) 13 In the re-issued IS 801 Indian cold formed steel design, the combined bending and shear check to clause 6.4.3 has been modified such that it now uses the clear distance between flanges to calculate the allowable compressive stress f(bw) rather than the full depth of the section.
A) 14 The re-issued IS 801 Indian Steel Design Code has been modified such that the shear checks now include a more accurate calculation for shear capacity to address an inaccurate shear area calculation used in the V8i versions.
A) 15 The method used inside the analysis engine to process analysis capabilities have been re-architected. This update should have no effect in any analysis capabilities or results, but allows for a more streamlined method for extending the engine capabilities in future.
A) 16 The range of static seismic load definitions has been extended to now include the loading defined in IBC 2018.
A) 17 The AISC 360-10 design module has been updated for the design of slender tube/box sections. Previously the effective area could be overestimated and result in an over estimate of capacity. Note that this only applies to the 2010 version of the code.
A) 18 The AISC 360-10 design module for box profiles has been updated such that when using equation F7.2 to calculate the effective width of the slender element, the component will also ensure that the value of b_eff is always greater than zero and less than b. Note that this issue only applies to the 2010 version of the code.
A) 19 The AISC N690-1994 design module has been updated such that the default value (i.e. if not specified in the model) of STYPE, the type of material, will be taken as 0.0 I, i.e. not Austenitic Stainless Steel. Note that this parameter will determine the values of Fe' used in eqn Q1.6.1a and Fa in clause Q220.127.116.11
A) 20 The STAAD.Pro Advanced analysis option for performing a geometric non-linear analysis has been updated to ensure that intermediate member results account for the changes that have occurred at each step during the iterative analysis process.
A) 21 The steel design module for EN 1993-1-1 has been updated to improve processing of profiles defined as GENERAL sections such that an erroneous warning message reporting that 'Plastic and/or elastic section moduli not defined in user table' is not reported when the properties have been defined.
A) 22 The processing of external User Provided Tables (UPT) has been improved. Now, any external UPT file having a valid file path can be opened. However, a couple of additional tests has been added to validate the filename. the length of the filename with path cannot exceed 72 characters, and cannot include the " - " character would be interpreted as a line continuation marker.
A) 23 The Indian concrete design module IS 456 has been updated the processing the CLEAR parameter used to identify the cover to the main reinforcement. Previously this would be correctly processed if the assignment is defined with the text ALL. However, when the assignment method used the option LIST and a member list, this parameter was not correctly processed.
A) 24 The Indian concrete design module IS 456 has been updated to ensure that if the parameter BRACE 1 is specified for the design of a beam, that is that the axial force be included in the beam design, the sign of the axial force at the end of the member is correctly considered.
A) 25 The AIJ steel design modules (2002 and 2005) have been updated to provide additional options for the Von Mises checks. There two additional methods providing options for determining the direct stress sigma(x) with or without including the effect of torsion in the value of tau(y). Refer to the help document for Japanese steel design for more details on implication of selecting these options.
A) 26 The AIJ steel design modules (2002 and 2005) have been updated to improve the determination of the moment magnification factor. The indication of single/double curvature is determined solely on the end moments on the member. Previously the program was determining double curvature if the moment changed side of the neutral axis at some point along the length of the member which may not the intent of the code.
A) 27 The IS 801 Indian cold formed steel module has implemented a revised calculation for Iyc which was found to be defective in the V8i implementation of the code and potentially significantly underestimating the bending stress.
A) 28 The Russian steel design modules SP 16.13330.2011 and SNiP 2.01.07-81 have been updated with a new parameter GMF to indicate the ratio between the design and characteristic loading. The default value being 1.0. The parameter RATIO is used purely to identify the limiting ratio for applied effects compared to the permissible capacities.
A) 29 The AISC 360-16 steel design routine for web tapered wide flange sections has been updated to ensure that the design of member used the appropriate forces at each section. Previously this would have used maximum forces along the member for the design at each section resulting in a potentially over conservative design.
A) 30 The AISC 360-16 steel design routine for wide flange sections with differing flange sizes has been updated with a more accurate shear centre calculation and additionally adds a check to ensure that if a wide flange section with differing flanges is specified, this is treated as a built up profile rather than rolled (i.e. as defined with the STP 2 parameter).
A) 31 The output of web tapered wide flange sections designed with the Japanese steel design modules AIJ 2002 and 2005 have been updated to include the calculated value Zx which was previously being reported as 0.0, although the calculated value was being used in the design.
A) 32 A limit of 1000 members associated with a CHECK CODE command with the AIJ steel design has been removed.
A) 33 An additional validation check has been added to the processing of a seismic load assignment applied in the Y direction to ensure that the torsion options are not applied as these are only intended for horizontal directions, i.e. X and Z.
A) 34 The processing of the Russian wind load command has been updated to catch an incorrect specification of SNIP 2016... when the command should be entered as SP20 2016…
A) 35 The two buckling analysis methods have been updated to provide a method of using either method in STAAD.Pro Advanced whilst still retaining use of the advanced solver.
A) 36 The AISC N690-1994 design module has corrected the implementation of the equation Q1.6-3 which did not correctly account for the fa/Ft term when evaluating the interaction equation and the factors SMY, SMZ were being applied to the actual stresses rather than the allowable stresses.
A) 37 The interaction check for clause H 1/2/3 in the AISC 360-16 steel design routine has been updated to ensure that the value of moment cpacity Mx is taken for the current load case being checked rather than the minimum of all the load cases being considered.
A) 38 Not Used (issue documented in TFS 1011902)
A) 39 The method used to process Ritz Vectors for multiple load cases has been updated to address situations which could result in multiple simultaneous access to a temporary file and would case the analysis to terminate.
A) 40 The new feature that allows the dynamic wind loading module for the Russian SP 20.13330:2016 code released as technical preview feature in the V22 release is now available as a fully commercial feature.
(B) Generic GUI Updates (06)
B) 01 Additional checks have been added for models that include definitions of composite decks. This facility is only intended for concrete decks on steel supporting beams. Both the GUI and analysis engine have been updated to test that steel beams have been used.
B) 02 The section properties of the Indian cold formed sections have been updated to be consistent with IS 811-1987 (Second Edition) - Reaffirmed 2004
B) 03 The Info page has been updated in the backstage with the re-introduction of the 'Comments' in the Job Information section. Note that the comment is a single string entry. If multiple entries of JOB COMMENT are included in the file, only the first will be displayed.
B) 04 The file parsing/processing functions used when opening a model has been updated with significantly more efficient processing routines. This can result in a major reduction in the time needed to load a model into the GUI.
B) 05 The method to provide a CONNECT Project settings has been deprecated and the options removed from the Configuration dialog.
B) 06 A primary routine used when a file is opened to process the commands has been restructured to markedly improve the performance of the file open event.
(C) Analytical Modelling Workflow (11)
C) 01 The design parameters for the re-implemented Indian cold formed design code IS 801 have been updated with the correct definitions for LX, LY, LZ, KX, KY and KZ.
C) 02 The GUI method for displaying loads has been updated to address an issue which prevented loads from being displayed if the model had been previously opened in a V8i version of STAAD.Pro due to a change in the format of the ancillary file *.SLG . This did not affect the analysis.
C) 03 The Rendered 3D view has been enhanced to support the use of the keyboard arrows to rotate the view in the same way as rotating the standard model view.
C) 04 The routine that is used to display 3D sections on the model has been updated to ensure that when reading the data for Japanese sections (other than angles and circular hollow sections), uses the correct dimension conversion. Note that if the model was closed and re-opened, then the correct conversion was used, also this issue was only in the display and did not affect any analysis.
C) 05 The values of AX provided for PIPE sections in the AISC v15 database have been updated to include the values upto 3 decimal places. Previously this was truncated to one decimal place.
C) 06 The AISC V15 database has been updated to ensure that the Tube table includes a primary key which is needed to allow the database to be edited. Previously, if the database was edited and the changes committed, the program would crash and the changes not saved.
C) 07 The Section Database Manager dialog to specify the Default database has been updated to ensure that the selected database matches the name displayed in the main contents panel
C) 08 The Beam Query dialog has been updated to ensure that the thickness of the web for cold formed channel sections is reported as the value of 't' in the database rather than the radius 'R'. This was purely a dialog drawing issue and did not affect any analysis or design routines.
C) 09 An additional selection cursor provided in the V8i version of STAAD.Pro has been reintroduced that allows displayed loads to be selected and edited.
C) 10 The Beam Query dialog 'Property' sheet has been updated to report the shear areas AY and AZ for tapered tube sections using the same method as that in the analysis engine.
C) 11 The GUI processing of the AISC 360-16 SLF parameter has been updated to ensure that the value is handled as a floating point number rather than an integer.
(D) Physical Modelling Workflow (05)
D) 01 The Physical Model workflow has been extended with the capacity to define static seismic and dynamic definitions including response spectrum and time history definitions, which are hosted in the model catalog and can be used in appropriate load cases. New Load Case Categories have been added to support these new definitions and a new sheet has been added to the Options dialog to allow dynamic settings to be defined including an option to Calculate Eigen Solutions which will create a modal load case in the analysis model if no specific dynamic load case has been included.
D) 02 The method to merge members into single physical members has been extended such that it is now possible to select multiple, unconnected members and the merge routine will aggregate the members into collections of members that can be made into valid physical members without having to go through each set individually.
D) 03 The method for defining a new UCS with the WCS alignment, has been updated to ensure that the vectors defining the local X and Y axes are 1 m long when using a Metric system or 1 ft long when using English units.
D) 05 The assignment of materials onto the model using the Assign dialog and using the 'Source' option as 'Model', i.e. materials already defined in the model, has been updated to allow this method. Previously this option would not assign the material.
D) 05 A check has been added to ensure that the Physical Modelling Workflow is launched from within the main STAAD.Pro environment to ensure that the data for physical and analytical models is correctly managed.
(E) Other Modelling Workflows (00)
(F) Analysis Post Processing Workflow (03)
F) 01 The 3D Beam Stress Contour diagrams for composite sections has been updated to correctly account for the section properties with differing materials
F) 02 The 3D Beam Stress Contour routine for processing a hexagonal tapered tube has been updated to use better stress locations and correct the calculation to determine the stresses at those locations.
F) 03 The design results from an IS 801 Indian cold formed steel design was not correctly being reported in the Beam Query dialog. The data has been re-formatted and now correctly reports load case and design forces.
(G) Other Post Processing Design Workflows (08)
G) 01 The method used to launch RAM Concept from the Advanced Slab Design Workflow has been updated to ensure that if RAM Concept is installed, the location of the program is correctly identifed and the application launched with the data from the STAAD model.
G) 02 The Connection Design Workflow has been updated to ensure that the ribbon options for 'Select all Horizontal Column-Beam-Brace joints' and 'Select all horizontal Beam-Beam-Brace joints' are displayed as active. These connection types were added in STAAD.pro CE Update 3, but the selection methods were not activated.
G) 03 The interop with STAAD Foundation Advanced has been updated to better handle a variety of circular column profiles including those defined in a standard database as Pipe, HSS Round, Solid Round or defined as a PRISMATIC Circle or a PIPE section in a user table.
G) 04 A component, SandDock for Windows, required to operate the Steel AutoDrafter workflow was not activated when included in the V21 Update 3 release as a technical Preview. This issue was addressed in the following commercial release 22.00.00.15, but the fix was not documented.
G) 05 The integrated version of RAM Connection used in the Steel Connection Design Workflow has been updated to support localisation. Although there is no modification in the English release, this capability will be utilised with future localisation packs for STAAD.Pro.
G) 06 The interop with STAAD Foundation Advanced has been updated to include details of any assigned beta angle applied to the column member along with the column dimensions.
G) 07 The Steel AutoDrafter workflow has been updated to use the section profile data defined for physical members as well as analytical member properties.
G) 08 The Steel Connection Design workflow has been updated to now include support for connection designs to the Australian design code. Refer to RAM Connection for more details on the design capabilities for the design to the Australian code.
(H) Interoperability (00)
(I) The Editor, Viewer and Other Modules (05)
I) 01 The Steel AutoDrafter workflow has been enhanced with an option to take a drawing and push directly into a copy of MicroStation or PowerDraft in a similar fashion to the method provided in RCDC.
I) 02 A segment of the GUI that was previously hard coded with English text has been serialised such that now more of the GUI is available for the localised version of STAAD.Pro.
I) 03 The FreeSketch module of Section Wizard has been updated to allow any profile that has been defined and exported to a GENERAL shape User Table file, will include the outline of the shape so that when it is used in a STAAD.Pro model, the shape will be rendered in the Rendered 3D View or when 3D sections are included on the general model view.
I) 04 The FreeSketch module of Section Wizard has been updated to restrict import of shapes defined in a drawing file to only DXF files.
I) 05 The option to set the Editor as 'Always on Top' has been updated to ensure that when set, the Editor uses this setting.
(J) OpenSTAAD (01)
J) 01 Four new OpenSTAAD functions have been added that assist in managing the load cases in a STAAD file:- DeletePrimaryLoadCases(PrimaryLoadCaseNos, bReferenceLoads); DeleteReferenceLoadCases(varReferenceLoadCaseNos); ClearPrimaryLoadCase(varLoadCaseNos, bReferenceLoads); ClearReferenceLoadCase(varLoadCaseNos)
(K) Documentation and Printing (05)
K) 01 The AIJ steel design codes 2002 and 2005 have had a minor typo corrected in the calculation for allowable compressive stress (sections D 9.B.2 and D 9.C.5 )
K) 02 The routine used to print a command file from the main GUI rather than from the Editor has been updated to address a conflict that resulted in the program crashing.
K) 03 Additional clarification on the methods used for both the iterative and eigen buckling analysis has been provided in sections TR.37.4 Buckling Analysis, G.17.2.2 Buckling Analysis, G.18.104.22.168 Iterative Buckling Analysis and G.22.214.171.124 Eigen Buckling Analysis.
K) 04 Additional control has been added to the settings dialog for the Editor and Output Viewer in order to allow the size of the margins of printed documents to be controlled.
K) 05 The print preview routines have been updated to ensure that if this is run several times in a session and the report includes then excludes steel design data, would not cause the program to crash. Also an additional memory allocation issue that was associated specifically with the ASME NF 3000:2004 design data which if included in the user report, would cause the program to crash has been addressed.
(L) Licensing / Security / Installation (04)
L) 01 In order to assist in tracing issues in the event of a crash, a new logging system has been added which will record the events in %LOCALAPPDATA%\Bentley\Logs\StaadPro.log.
L) 02 A sample model for defining an IS 801 cold formed steel design for a channel with lips has been added to the installation.
L) 03 Two additional verification examples have been added to the installation for steel design to the CSA S16-01 steel design code. These relate to examples published in the Handbook of Steel Construction, Ninth Edition (fourth printing 2008).
L) 04 The STAAD.Pro installation has been updated to include V9.1 of the STAAD Foundation Advanced installation.
