(A) Issues addressed in the Analysis/Design engine (42)
A) 01 The AISC 360-05 design module for tapered sections and those defined as I sections in a UPT has been updated to improve the calculation of the equal area axis used in the calculation of the plastic modulus and thus the capacity BEND-Z. The previous results were conservative.
A) 02 The EN1993 steel design module has been imporoved for angle section design. For class 4 sections the basic elastic section modulus was being used in place of the effective section modulus of the class 4 section.
A) 03 The EN1993 steel design module has been updated to correct the calcuation of eqn 6.2 when the parameter ELB was set to 1. The value of Nrd in equation 6.2 ratio calculation should use the section capacity but was using the buckling capacity, which produced conservative results.
A) 04 The NORSOK N004 design code has been updated to correct the calcuation of Qu for axial force which was being calculated the axial force being applied in the opposite direction, i.e. For compression when the member was in tension and visa versa.
A) 05 The analysis engine has updated the calcuations in the IBC 2006 seismic loading to handle situations where the calculated upper limit of Cs is below the lower limit of 0.01.
A) 06 The Australian concrete code has been updated to ensure that the correct load case is reported in the Member Query dialog for beam and column members.
A) 07 The AISC 360-05 deflection check has been updated to esure that the correct length over deflection check is performed.
A) 08 The Eurocode 3 steel design has been updated for user defined class 4 sections. While calculating the moment reduction factor, the "effective" section's moment of inertia was being used instead of its section modulus. This gave rise to incorrect reduction factors and hence a low value for the LTB moment capacity.
A) 09 The Australian concrete batch design ouptut sketch for AS3600 has been updated to correctly report the governing load case and reinforcement sketch. However, it is strongly recommended to use the more comprehensive AS3600 design module in the Concrete Design mode.
A) 10 The Direct Analysis routine has been improved for situations where the DEFINE DIRECT ANALYSIS option includes the setting of NOTIONAL LOAD >=0.0029 which indicates that an iteration on tau_b is not required and that not all members are defined as their flexural stiffness as being significant. Whilst the anayisis and defelctions were being reported correctly, the end moments were not always correct.
A) 11 The output report for an IS456 concrete design has been updated to support displaying larger numbers which previously would be displayed as ****
A) 12 The EN1993 steel design routines when including the Netherlands National Annex have been improved. Previously the additional clause check for Cl.6.3.3 (and hence the NEN C.l 188.8.131.52.3) was being done for all cases of axial compressive load. This check should only be done in case of combined axial and bending loads. This issue has been rectified and a check has also been included to ignore this check if the bending moments are very small when considering the combined axial + bending condition.
A) 13 The routines for calcuating the centre of mass when using a response spectrum defined as either IS1893 or Eurocode 8 have been improved to address situations where no global Y loading has been defined, which is the basis on which centre of mass is calculated, and the program will attempt to use global X or Z loads instead. In the load to mass conversion, this occationally resulted in very small global Y masses being created and thus these were used as the mass model.
A) 14 The AISC 360-05 steel design module has been updated to use the member defined Youngs Modulus in calculating the compression capacity rather than the fixed value of 29000 ksi.
A) 15 The AISC ASD design routine for channels bent about their major axis has been updated to make use of equation (F1-8).
A) 16 The AISC 360-05 design routines have improved to include the calcuation of Cv as determined in Chapter G, section G2, using all three equations (G2-3), (G2-4) and (G2-5).
A) 17 The batch processing Chinese steel and concrete designs have been withdrawn and more comprehensive design solutions provided. SSDD for steel design and the Concrete Design Mode.
A) 18 The BSK99 design code has been updated to ensure that the results are always displayed in KNs and Metres.
A) 19 The DIN 1880 steel design code has been updated to ensure that the classification of User Defined Wide Flange sections are checked and the overall section is classified appropriatly.
A) 20 The ACI 318-05 design module in the batch processing mode has been updated to ensure that the minimum requirements are met including the provision of clause 10.5.3.
A) 21 The analysis engine has been updated to ensure that if a PEFRORM DIRECT ANALYSIS is included for some load cases and some other form of analysis for others, the DIRECT ANALYSIS does not affect the results generated of the other load cases.
A) 22 The AISC 360-05 design code has been updated to ensure that when the minor axis plastic property is used in the calculations for wide flange section, the full plastic property is used.
A) 23 The legacy European database has been updated with the correct column heading for IX and IY for IPN sections.
A) 24 The GNL analysis has been updated to save the transverse shear and bending moments at the centre of plates in addition to the three inplane forces previously saved during the analysis.
A) 25 The Canadian steel design code has been updated to ensure that if tension only members are defined with self weight loading which theoretically can induce compression loading, this is not used to trigger the slenderness checks for compression members.
A) 26 The AISC 360-05 design code has been updated to ensure that the moment for the correct axis is reported in the CL.F-Minor data section of the output. The calcuations were done useing the correct values.
A) 27 The design modules have been updated to ensure that section profiles that included either '(' or ')' in their section names were treated as valid section names which was a particular problem in the aluminium section design where some standard tables included these characters.
A) 28 The IS3920 code has been updated to ensure that the calcuation of EUDL is correctly noteably when the SELFWEIGHT command is assigned to a member list and the GLD parameter is used.
A) 29 The processing of USER TABLE wide flange sections defined with a composite flange has been updated to ensure that the additonal self weight resulting from the additional flange is accounted for.
A) 30 The AIJ steel design module version 2002 has been updated to ensure that this is the reported version in the output file.
A) 31 The analysis engine has been updated to include a warning in the output file if a SELFWEIGHT load command and assigned to a list of members as a note to the user to check that the list includes the actual range of members required.
A) 32 The IBC 2006 calcuations have been improved for metric models. The calcuation of Ct has been updated to ensure correct unit conversion using Ct(english) = Ct(metric)*(100/(2.54*12))^x where x is the supplied exponent.
A) 33 The Indian concrete design code IS3920 has been updated to ensure that if a combined member (defined using the COMBINE command) is designed followed by an un-combined member, the program did not correctly consider the effective UDL on un-combined members.
A) 34 The GUI has been updated to correctly display floor load commands which have been assigned using the XRANGE option. Additionally, the analysis engine has also been updated to ensure that the correct members have been loaded when the XRANGE option has been used with the FLOOR command.
A) 35 The Canadian steel design module CSA S16-01 has been updated such that the moment of resistance of beams subjected to axial tension and bending is reported to either equation 13.9a or 13.9b as necessary.
A) 36 The wind loading routines have been improved to ensure that wind loading on open structures can be limited to a section of the model using a member list.
A) 37 The wind load generation routines have been updated to prevent the creation of additional loading resulting from smaller wind panels being defined which are subsets of larger panels.
A) 38 The EN1993-1-1:2005 module has improved the torsion calcuations when the value of (z/a) is very large which would report clause 6.2.7(1) as having a result of *****
A) 39 The BS5950-5 cold formed steel design module has been updated to ensure that the slenderness calculation uses the correct effective length and the equation to calculate the critical buckling moment (cl. 184.108.40.206) has been updated. Additionally, the output has been updated to ensure that the shear capacity is included.
A) 40 The Norwegian NS3472 design module has been updated to support European CHS, SHS and RHS sections as well as the tubular sections TUBE and PIPE previously supported.
A) 41 The SNiP steel design routine has been updated such that the output reported when the critical check is axial (i.e. tension or compression), only the axial force was included. The moments were shown as zero.
A) 42 The Chinese steel and concrete design modules have been removed from the analysis processing engine. Concrete design is maintained with the Concrete Design Mode and steel design with the SSDD application.
(B) Issues addressed in the Pre-Processing Mode (28)
B) 01 The STAAD.Pro GUI has been updated to better handle files that have errors included. If the file has been opened in a STAAD.Pro session that has been used to open and view a number of files, then attempting to open a file which has had errors that have been fixed in the Editor could cause the GUI to crash.
B) 02 The GUI has been updated to ensure that it makes use of the unit fields defined in the section database files (i.e. *.MDB) when scaling the sections in the GUI. Note the engine and thus the analysis made use of these appropriately and thus this did not effect the results.
B) 03 The GUI has been updated to better handle old versions of ProjectWise and ensure that the GUI does not crash if attempting to use old ProjectWise installations. The STAAD.Pro integration with ProjectWise requires a version of 08.11.07.00 or greater
B) 04 The GUI has been updated to ensure that it can support the correct allowable range of values for the EN1993 steel design parameter ELB.
B) 05 The GUI has been updated to improve the handeling of IBC 2006 data to ensure that when a file is opened with IBC 2006 load data which is displayed in the load edit dialog, the correct Site Class is displayed.
B) 06 The Jindal database has been updated with additional sections available from Jindal.
B) 07 NBC 2005 combination rules added to the Auto Load Generator
B) 08 The hydrostatic plate loading routine has been enhanced to allow plates to be loaded where the definition of the loading is negative.
B) 09 The GUI has been updated to ensure that when Reference Loads are defined, the file is saved with UNIT commands in the correct location.
B) 10 The GUI has been updated to ensure that it correctly reads a file with Algerian siesmic load data (RPA). Whilst this would analyse correctly, if the file was re-saved from the GUI, the weight associated with the siesmic data was not saved correctly.
B) 11 The GUI has been updated to ensure that when a Eurocode 8 response spectrum is defined, the values displayed in the loading dialog are in the current units, not just in m/s2 which was previously done.
B) 12 The cold formed steel design module BS5950-5 has been updated to include the LTB capacity of sections in the TRACK 2 output.
B) 13 The GUI has been updated with a data check for when uniformly distributed loads have been defined with an explicit start and end position as 0.0.
B) 14 The GUI has been updated to handle Response Spectrum commands which include the MIS 0 parameter. This indicates that the missing mass should be accelerated at the frequency specified by the ZPA paramater, or 33Hz if ZPA has not been specified. Previously if MIS 0 was included in the file and resaved from the GUI, this command was removed.
B) 15 The timber design parameter list in the GUI for Eurocode 5 has been updated with KLEF and SERV removed as these were not implemented and produced warnings if used in the file.
B) 16 The GUI dialog for the Algerian siesmic code has been updated to correctly display the label of 'Structural Quality Factor' which was previously shown as 'Importance Factor'
B) 17 The GUI has been updated to correctly handle deletion of user created orthotropic 2D materials.
B) 18 The Member Query dialog has been updated to display the torsion inertia IX for wide flange sections recorded in the database rather than being calculated based on the basic shape dimensions as done previously.
B) 19 The angle section table in the Canadian steel section database has been updated so that the radius of gyration is that of the principal axes, not the geometric axes which were previously included. Although the actual vlaues used by the program are internally calculated and not acfected by the values shown in the tables.
B) 20 The GUI has been updated to better handle 'Partial Surface Trapezodial Loads'. Once defined, if a load is edited by double clicking on it in the Loads dialog, the data is correctly loaded and saved from the dialog.
B) 21 The AISC Tube database has been updated to correctly include the plastic modulus in the minor axis. This did not cause a problem as this value is not used in the analysis or design modules. If needed, the plastic moduli are calculated based on the section dimensions.
B) 22 The Floor Load generation routine has been improved to ensure that when closed loops of beams are identified, they do not contain smaller loops which are loaded seperatly.
B) 23 The Section Profile Tables dialog has been updated to ensure that if a wide flange section is selected and a double profile (D) option is selected, then the defintion and edit box to allow the spacing to be defined is activated.
B) 24 The GUI file reading routine has been updated to ensure that it correctly recognises the FLOOR HEIGHT command as used in the IS1893 siesmic analysis.
B) 25 The GUI has been updated to maintain the graphical view when changing between pages when practical rather than reseting settings such as the zoom that may have been set.
B) 26 The GUI has been updated such that if a new material is assigned to a model such that any previously assigned material is no longer assigned on the model, the command line assigning the material is fully removed. The definition is not removed.
B) 27 The GUI has been updated to ensure that macros which are added to the User Tools menu are displayed in the toolbar.
B) 28 The dialog box that allows the selection of entities by a range perpepdicular to the global planes has been updated to ensure that the correct length unit that will be used is displayed.
(C) Issued Addressed in the Post-Processing Mode (10)
C) 01 The recent enhancement with the Response Spectrum command that allowed additional load cases to be created based on the mode shapes has been updated to ensure that the GUI is kept current with the created load cases if there are changes made to the starting load case number and the analysis re-run.
C) 02 The post processing display of time history displacements have been updated to better handle metric units .
C) 03 The post processing reporting of beam relative displacements has been improved to ensure that the values are correctly converted from global to local axes systems.
C) 04 The GUI post processing module has been updated to ensure that the element results reported for elements which have been made inactive are reported as zero. Note that the results reported in the output file were correct.
C) 05 The post processing display of nodal displacements of models with Eurocode 8 response spectra has been corrected to display the maximum displacements (which were previously displayed as zero).
C) 06 The AISC ASD design routine has been updated to correct a recent modification which resulted in the allowable stress reported in the Member Query dialog not being displayed correctly. The correct value was being used in the design and printed in the output file.
C) 07 The FLOOR LOAD GENERATOR routine has been improved to deal with situations where all the nodes of a selection do not all lie in a plane. The tolerence was set as 1mm. This can now be controlled using a new SET command, namely SET FLOOR LOAD TOLERENCE f, where f is the tolerance in the current length unit. This SET command can be located anywhere in the input file before the loading although GUI (COMMAND -> Miscellaneous -> Set Floor Load Tolerance) will put it at the top of the input file between the STAAD and JOINT COORDINATE commands.
C) 08 The routine for calculating the Transfer forces has been updated to ensure that the values that are reported ar in the current units. Previously the force would have always been in Kip units.
C) 09 The Post Processing module GNL graph tool has an option to 'Limit Maximum Load Step for Graph' which displayed the incorrect message if an inappropriate load case was selected to display.
C) 10 The Post-Processing of the DD ENV 1993-1-1 has been improved so that the correct headings for MCZ (major axis moment capcity) and PC (compression capacity) are displayed in the Member Query dialog box on the Steel Design sheet.
(D) Issues Addressed in the Steel Design Mode (01)
D) 01 The Steel Designer Module BS5950-1:2000 design module has been updated to ensure that members which are not over utilised are not displayed as UNSAFE.
(E) Issues Addressed in the Concrete Design Mode (03)
E) 01 The RC Designer module has been updated to ensure that design codes that used a shared DLL for passing section data which included IS456, BS8110 and CP65 are able to so.
E) 02 The ACI 318-05 design module in the Concrete mode has been updated to correct the printout details for bi-axial moments which were those based on the EC2 2004 code, so both the nomenclature for the capacities and moments, and the printed values were wrong. The Pass/Fail ratios were correct however. This is now changed to use the correct terms and to show the capacities and moments in the correct units. The value of Phi used is also added to the printout.
E) 03 The AIJ Beam Brief in the RC Designer mode has been updated to ensure that if a negative concrete strength is defined it does not cause the application to crash.
(F) Issues Addressed in the RAM Connection Mode (03)
F) 01 The RAM Connection module has been updated such that it can handle base plate designs with columns which have defined beta angles in excess of 180 degrees.
F) 02 The RAM Connection module has been updated to ensure that if the loadcases to be considered in a design are modified these are correctly accounted for if a connectin is re-designed.
F) 03 The beam splice connection in the RAM Connection module has been updated to ensure that the connection can be assigned to members that are correctly co-linear.
(G) Issues Addressed in the Advanced Slab Design Mode (02)
G) 01 The Export of a slab to RAM Concept has been updated to address a unit change issue. If a model was created and exported, then the base unit system is changed and the model re-eported, the revised model did not correctly reflect the change in unit system. This has now been addressed.
G) 02 The RAM Concept export routine has been improved to ensure that columns that are defined with a local X axis pointing in the positive global Y axis and a beta angle are rotated correctly in RAM Concept.
(H) Issues Addressed in the Piping Mode (0)
(I) Issues Addressed in the Editor, Viewer and other modules (06)
I) 01 The Editor has been updated to correct a command parameter error when processing files with a list of plate elements identified with the MEMB string which was incorrectly being reported as an error.
I) 02 The OpenSTAAD documentation has been updated to clarify that functions such as Output.GetOutputUnitForDisplacement return the string of the labels used for displaying the results in the GUI.
I) 03 The IS800 Technical Reference manual has been updated to correctly list the available design parameters.
I) 04 The OpenSTAAD documentation has corrected the information that indicates that the parameters assigned to the Results Object function GetMemberIncidences should be of type Long, not Integer.
I) 05 The CIS/2 import module has been updated to better handle STP models that have been defined with both numeric and alpha numeric references. If the member number is defined in the STP file, then this is used, however, if a text string is used to reference the member then STAAD will allocate a member number. If later in the file a member is defined with a member number this could cause a problem. Now STAAD will read in all the member definitions before allocating member numbers.
I) 06 Details of design codes supported by STAAD.Pro have been added to the online help in the Welcome section.
(J) Issues Addressed in OpenSTAAD (01)
J) 01 The OpenSTAAD function AreResultsAvailable has been updated to ensure that it returns the correct status
(K) Issues Addressed with Printing (02)
K) 01 The User Report routine has been updated to ensure that it handles the temporary situtation when all items have been removed from the report setup prior to adding new items for the report. Previously this condition when there wer no included items could cause the program to crash.
K) 02 The releases table in a user report has been updated to identify the directions which are free and have spring connections defined.
(L) Issues Addressed with licensing / security / installation (0)
