7.1 Graphical Interface
7.2 STAAD Analysis and Design

7.1 Graphical Interface

The following item has been improved in the STAAD/Pro Graphical Interface. The mesh generation facility for creating plates with holes (in StWizard) has been simplified. The following errors have been rectified in the STAAD/Pro Graphical Interface.

1. If the input file contains the "DEFINE 1893 LOAD" command, while saving the file from the STAADPRO GUI, the "B" parameter may not be saved.
2. If a UNIT statement if defined following the PARAMETER command and before the CODE command, it may be flagged as an error when the file is opened in STAAD/Pro.
3. When an alloy is selected for assignment as a parameter for design per the Aluminum code, the Alloy number saved in the STAAD input file will be one less than the correct value. For example, if 6061-T6 is chosen, the value ought to be 34, but the value written is 33.
4. If a file containing the DELETE MEMBER command is opened, the graphical representation still displays the members which ought to have been deleted. Further, if an analysis is performed and the Post-processing mode is selected, erroneous messages are displayed.
5. The Canadian steel design parameter list displayed is incomplete.
6. If a file is saved from the STAAD/Pro GUI, the information is written into the STAAD input file in a manner that the width of the lines exceeds the limit of 79. Consequently, the analysis engine is unable to process these files.
7. The "Break All" facility in the Geometry menu does not work correctly in some situations.
8. The Australian steel design parameter list displayed is incomplete.
9. The parameters for maximum and minimum depth restriction in the LRFD parameter list are incorrectly listed as MAX and MIN instead of DMAX and DMIN.
10. The MMAG parameter is missing from the Indian concrete code parameter list.
11. The cut-section facility in the Tools menu does not work correctly in some situations if the criteria used for selecting the section location is a node number.
12. If a Trapezoidal load, acting only on part of the span of a member, is applied, the start and end locations of the load are not saved when the command is written into the input file. As a result, the analysis engine assumes that the load spans over the full length of the member.
13. While saving a a file containing the AISC ASD parameter PROFILE, the values may not be saved correctly. For example,
    
    PROFILE W12 W14 W18 ALL
    
    may be incorrectly saved as
    
    PROFILE W12 W12 W12 ALL
14. Open an existing model containing MEMBER PROPERTIES assigned per a specific steel table. If the user wishes to assign a new set of properties or alter the existing set by assigning from an alternative steel table, that is not permitted.
15. The Quick Print option fails to print member dimension lines and markings.
16. Split beam operation fails to split associated loads on the member.
17. The Australian code is not available as an option among the list of Concrete Design codes and parameters list.
18. There are duplicate instances of the KY and KZ parameters for the Japanese steel code.
19. The Cb parameter is missing from the Japanese steel code parameter list.
20. The description of the BEAM parameter for the American LRFD code is erroneous.
21. The MAIN parameter is missing from the American LRFD code.
22. The option "File menu - Export Report - MS Word File" isn't working correctly.

7.2 STAAD Analysis and Design

The following errors have been rectified in the STAAD/Pro analysis and design facilities.

1. On Windows 95 and Windows 98, if a non-US code is selected as the default code during installation, that information is not correctly registered. Consequently, the Analysis engine corresponding to the US design codes is the one always selected by default.
2. On Windows 95, the STAADPRO analysis module may crash immediately upon launch with an error message involving the expressions "kernel32.dll" and "GetDiskFreeSpaceEx".
3. If any of the following:
   
   joint numbers, member numbers, plate numbers, solid numbers
   
   are not in ascending order, but in some arbitrary order including a descending order, the results corresponding to that item in the Post-processing mode will not be displayed correctly. However, the values reported in the output file (.anl extension) will are correct.
4. In composite beam design per the AISC ASD code, the value reported for number of shear connectors may sometimes be negative.
5. When load list commands are specified in between steel design commands and if deflection check is among the design criteria, the correct deflection value may not be used in the calculations.
6. For steel design per AISC ASD, if the RATIO parameter is assigned a value larger than 1.0, the values of Fey and Fez (which are the Euler stress values calculated according to the equation shown at the bottom of page 5-54 of the code) may be overestimated by an amount whose extent is the same as the RATIO.
7. For design of beams for flexure per the ACI code, the values reported for bending moment may be 1/12th of the correct number. However, this is only a reporting error and appears in both the positive and negative bending moment values reported. However, the area of steel required and provided will be calculated and reported correctly. The defect is present only under the following circumstances :
   
   a. Concrete beam and column design is done per the ACI code.
   b. The column design is done prior to the beam design.
   c. The input and output values for concrete design are in the the metric system.
8. If multiple ANALYSIS is performed using the CHANGE command, a crash may occur while performing the triangular factorization for analysis of the structural condition after the CHANGE command. This error is present only under the following circumstances :
   
   a. A CHANGE command is present.
   b. The SET NL command is present.
   c. Support conditions are defined before and after the CHANGE command.
9. In the Post-processing mode, if one clicks on the Query option and selects Concrete design (column design per the ACI code), certain values such as
   
   Fy, Fc, Bar Numb, Bar Size, etc. may appear as 0.
   
   This is only a reporting error. The values which appear in the STAAD output file are correct.
10. For steel design per the IS800 code, if the axial stress exceeds 60% of the Euler stress, the value obtained for the L.H.S of equation of Clause 7.1.1(a) of the IS800 code document will not be correct.
11. If the joint numbers of the structure are not in sequential ascending order, and if the member incidences are requested per STAPLE commands, the joint numbers of the ends of the members will be reported incorrectly.
12. If a LINEAR load is applied along the global direction GY, the program considers only half that load for the analysis.
13. For column design per the ACI code, if metric bar sizes are specified for the MAXMAIN and MINMAIN parameters, the program may falsely report that the bars are invalid, and proceed to use the default values for those parameters.
14. During aluminum design (code checking or member selection) of double angles and double channels, the section properties are not calculated correctly during the design. The values calculated are those of a corresponding single angle or single channel. This error occurs only during the design. For analysis purposes, the correct property values are used.
15. In composite beam design per the AISC ASD code, if the WID parameter (effective width of slab) is provided in any units other than Inches, the results of the composite design may be wrong.
16. If a LINEAR load is applied on tapered members, the contribution from this load will be either 0.0 or in a rather unlikely scenario, some random number. This has now been corrected.

6. What's New in STAAD/Pro 2000, Build 1007.US.REL, 1007.US.NET and 1007.US.CORP

6.1 STAAD Analysis and Design
6.2 Known Problems

6.1 STAAD Analysis and Design

The following items have been modified in the STAAD Analysis and Design Engine. For design per AISC/ASD code, if CMY, CMZ are provided, that value will be used regardless of whether or not SSY, SSZ are provided.

The following bug fixes have been made to the STAAD Analysis Engine.

1. If multiple arrival time values are specified and data is extended to several lines using line separators (hyphens), the analysis results may not be correct. This has now been rectified.
2. If a CQC combination is performed in a Response spectrum analysis, the analysis results may not be correct. This has now been rectified. This error dates back to all builds of STAADPRO 2000 preceeding this one.
3. An error related to analysis per UBC 97 code has been rectified.
4. If multilinear springs are defined and the list contains the word TO in it, not all the items in the list will be treated as having multi-linear springs. This has now been corrected.
5. An error related to stresses in solid elements for load combination cases has been corrected.
6. An error related to uniformly distributed loading along the local axes of tapered members has been corrected.
7. An error related to reporting of stresses in single angles in response to the command PRINT MEMBER STRESSES has been corrected.
8. An error related to linear loads on tapered members has been corrected.

6.2 Known Problems

I. Graphical Post-Processing

Stress values, reported in a tabular form in the Post-processing mode, at corners of single angles may be incorrect. Users should depend on the values reported in the output file under the command PRINT MEMBER STRESSES.

5.3 Known Problems

I. General

In certain cases, output viewer may print blank pages or pages with only header and footer. To solve this problem, delete the existing StaadVWR.ini file from \SPRO2000\STAAD folder (or the installation folder).

II. Graphical Interface

If user tries to load a STAAD/Pro input file with list associated to command more than 300 words, the program may crash. Current work around is to open the input file in an editor and break the list into multiple lists with less than (or equal to) 300 words. A patch to this problem will be available soon.
