Output viewer program is modified to take care of slow scrolling problem reproted for large output files. 6. Reported problem where the icon and view settings are lost after the editor is loaded is rectified. II. Post-Processing 1. Printing code is modified internally to be more stable. This modification should take care of some reported printing problems. 2. Inconsistencies related to "Beam Max. Relative Displacement" table is fixed. ------------------------------------------------------------------------------ 9.2 STAAD Analysis and Design The following items have been added to the STAAD Analysis Engine. 1. A new Material Definition command has been added 2. The STAAD Analysis Engine can now handle Composite Beam design 3. A new MODAL DAMPING feature has been added 4. New LOAD COMBINATION commands have been added for RESPONSE SPECTRUM loadcases 5. A Non-Linear Spring Definition command has been added 6. An ADVANCED analysis command has been added to the STAAD input file which will invoke the STARDYNE Analysis Engine 7. Modal extraction algorithm has been improved to calculate frequencies above 100 cycles/sec. 8. Additional output provided for torsion design per AISC publication T114 is implemented. The following bug has been fixed in the STAAD Analysis Engine. 1. Property names with more than 32 characters were not supported in earlier versions of STAAD/Pro. Now property names may contain more than 32 characters. 2. American Steel Table has been updated. 3. An error was present under the following conditions. 1) The input file contains plate elements. 2) Concentrated loads are applied on the plates using the ELEMENT LOAD option. 3) The coordinates of the location of the concentrated load are such that point of action of the load is one of the nodes of that element. The program userd to crash, or the output results (joint displacements, support reactions, element stresses, etc.) will indicate that the values of the results are "Nan" or "Infinity". This bug has been rectified. 4. The following bug related to INCLINED SUPPORT has been fixed. Description of the bug: If the input file contains inclined supports, the member forces and support reactions that are calculated may be wrong. Please note that the error is present if and only if INCLINED SUPPORTS are specified. To determine whether the analysis results are erroneous, you may do the following. 1) Create a backup of the STAAD input file (.std extension) for retrieval after the following test. 2) If the file contains MEMBER OFFSETS, temporarily remove them. 3) If the file contains load cases with RESPONSE SPECTRUM or TIME HISTORY load cases, remove them. 4) If the file contains the commands PDELTA ANALYSIS or NONLINEAR ANALYSIS, replace them with PERFORM ANALYSIS PRINT STATICS CHECK. Run the analysis. The output file will contain a summation of the total applied loading and total support reactions for each load case. If these values are equal and opposite, there probably isn't any error in your original analysis. However, if these values are NOT equal and opposite, it quite likely indicates an error due to the presence of the INCLINED SUPPORT command. 5. A bug releated to Steel Design per the AISC ASD, AISC LRFD, ASCE 52 Transmission Tower, Canadian CSA S16.1-94, Chinese GBJ 17-88 has been rectified. Description of the bug: If the critical section location for design happens to be at a location other than the end joint of the member, in some rare situations, some or all of the following may not be reported correctly in the steel design output : 1) The values of allowable section capacities. 2) The critical section location. 3) The load case number corresponding to the critical load case. 4) The section properties and design parameters used to obtain the critical design ratio. However, please note that the value of the critical design ratio as well as the values utilized in obtaining that ratio are correct. Hence, the critical ratio is both calculated and reported correctly. One of these rare situations is when the axial load at adjacent sections are of opposite sign, namely, tension at one section, and compression at the next, or vice versa. 6. A bug related to Steel Design per the Chinese code GBJ 17-88 is fixed. Description of the error : 1) If the maximum KL/r is less than 30 or greater than 100, Lambda for Equations 5.4.2-2 and 5.4.2-3 is not computed correctly. 2) Output for Track 1.0 does not provide the critical section location, forces, and ratio. 3) The Torsional constant value (IX) for I shapes and Channels is not right. 7. A bug related to Steel Design per the Canadian code CSA S16.1-9 Description of the error : 1) In the calculation of shear capacity along the local Y axis, there is an error in the implementation of Item (c) of Section 13.4.1.1 on Page 1-28 of CAN/CSA-S16.1-94. The error causes the quantity "Ft" to be underestimated, and consequently, the calculated shear capacity will be on the conservative side. 2) The shear capacity along the direction of the local Z axis for tubes is erroneously calculated as 0.9*AZZ*(0.66*Fy), instead of using the equation shown for Vr in Section 13.4.1.1. AZZ is the shear area for the tube, and can be obtained using the command PRINT MEMBER PROPERTY. Since AZZ is marginally smaller than Aw shown in Section 13.4.1.1, this will lead to a conservative value for VRZ as long as the h/w ratio for the local Z axis of the tube is small enough to cause Fs to be equal to 0.66Fy. However, if the tube dimensions are such that (0.66Fy/Fs) is greater than (Aw/AZZ), the results will be on the unconservative side. 8. The following bug related to member property command is fixed. Description of the error: If in an input file, some of the frame members are assigned member properties from the Aluminum table, and the remainder are assigned properties from steel tables, user provided tables, or using the prismatic facility,the program may crash while Processing Member Properties. 9. The following RESPONSE SPECTRUM analysis related bug has been fixed. Description of the error : If the response spectrum data (period vs. accn./disp.) specified in the input file is such that the first of those periods is greater than atleast one of the periods of the structure, the value of acceleration/displacement calculated by the program for those structure period(s) is wrong. 10. An assumtion related to moment capacity calculation has been changed. Description: In the AISC LRFD code, the moment capacity for all sections was calculated using the assumption that G, the modulus of rigidity, is 11200 ksi. From today onwards, it is based on 0.5*E/(1+n) where n is the Poisson's ratio. E and n are both input by the user under CONSTANTS, and if they are not, the program chooses default values. Since n is usually 0.3, and E is usually 29000 ksi, for default values of E & n, G will be 11153.85, marginally different from 11200. 11. The following problem related to Steel design per AISC-ASD and AISC-LRFD when TRACK 2.0 command is used has been fixed. Conditions required inorder for this error to manifest : 1) TRACK 2.0 is specified. 2) Load list command is specified for the steel design. 3) The last load case in the load list is not sequentially the last specified load case in the load data. Description of the error : The graph in the TRACK 2 output, which shows which load case is critical for each design location, will not be drawn. 12. Following problem in Floor load generation facility has been fixed. Description of the error : If the XRANGE and/or ZRANGE values are such that they are exactly the same as the coordinates of the boundary of the panel, the floor load applied on that panel may not be processed into member loads. To get around this problem, the user may expand the range just slightly so that the range is marginally outside the boundary of the panel. 13. Additional warning message is introduced. For frame members, if the Poisson's ratio (n) was not specified as an input under CONSTANTS by the user, the analysis would be performed on the basis of a value of 0.0 for n. From today onwards, if n has not been specified by the user, a warning message will be issued in the output file, and the program will choose a default value from a set of built-in default values. The Modulus of Elasticity for that member will be used as the criteria in selecting the default value. 14. Addition design parameter FU has been introduced for AISC-ASD 89 code and the AISC LRFD code. The ultimate strength of steel, namely, FU is now available as an input parameter for the AISC-ASD 89 code and the AISC LRFD 2nd edition code. The default value for it is 60 ksi. How this change affects steel design based on the AISC-LRFD 2nd ed. code. : The capacity in axial tension has to be computed as the smaller of 0.75*FU*NSF*AXX ----- (1) 0.90*FYLD*AXX ----- (2) Until now, FU was chosen as 1.05*FYLD. As a result, the capacity used to be governed by equation (1) most of the time. Now that the default FU has been raised to 60 ksi, it is more likely that equation (2) will govern. It also means that the capacity in axial tension used to be underestimated until now. How this change affects steel design based on the AISC-ASD 89 code. : The allowable stress in axial tension has to be computed as the smaller of 0.50*FU on the net area of NSF*AXX ----- (1) 0.60*FYLD on the gross area of AXX ----- (2) Until now, the program was calculating the allowable stress as 0.60*FYLD and the actual stress as FX/(NSF*AXX). This approach was leading to a design ratio that is more conservative than what the code permits. 15. Following defect related to eigen solution has been rectified. Description of the error : If an eigensolution is performed as a result of one of the following input items : a) The command MODAL CALCULATION REQUESTED is specified. b) A response spectrum analysis is performed. c) A time history analysis is performed. the program may fail to perform the eigenvalue extraction and report the error message *** STAAD-III ERROR *** A MODELLING PROBLEM HAS BEEN ENCOUNTERED WHILE SOLVING FOR MODES (E1) Temporary solution to overcome this error : One way around this problem is to specify a higher value for the number of modes that are to be extracted. If the "CUT OFF MODE SHAPE n" command is specified, increase "n". If this command is not specified, (as a result of which the programs attempts to extract the default number of modes, which is 3), the user may add this command after the specification of all CONSTANTs, as shown below. CUT OFF MODE SHAPE 5 16. Following defected related to concreate and steel desing in same run has been fixed. Description of the error : If the sequence of data in the input file is as follows : Concrete Design Steel Design Concrete Design Steel Design the analysis and design module crashes with a FORTRAN runtime error during the second steel design. Temporary solution to overcome this error : Change the sequence so that it is either in the sequence: Concrete Design Concrete Design Steel Design Steel Design or in the sequence Steel Design Steel Design Concrete Design Concrete Design 17. Following problem related to long output pages for steel design per Canadian code has been fixed. Due to improper placement of page break characters in the output file for the steel design output per the Canadian code, some of the output will not get printed. ------------------------------------------------------------------------------ 9.3 STARDYNE Analysis Non-Linear Time History Analysis has been added to the STARDYNE Analysis Engine. ------------------------------------------------------------------------------ 9.4 Mesh Generation A New Mesh Generation Module, based on OpenGL Graphics has been added to STAAD/Pro which will handle plates with holes. Users can now edit and save default prototype model information in a file of their choice. ============================================================================== 8. What's New in STAAD/Pro 3.1, Build 1005.US.REL, 1005.US.NET, 1005.US.CORP and Build 1006.US.REL, 1006.US.NET, 1006.US.CORP 8.1 Graphical Interface 8.2 STAAD Editor 8.3 STAAD Analysis 8.4 Stardyne Advanced Analysis 8.5 Design ------------------------------------------------------------------------------ 8.1 Graphical Interface The following items have been added to the STAAD/Pro Graphical Interface. I. General 1. A new option has been added to the File|Open dialog box to allow for bypassing the time consuming list (member, elements) checking checking. II. Pre-Processing 1. Pipe sections have been added to the section database for Australian, European, Korean and South African steel tables. 2. A new feature has been added to compute UPT properties from the key dimensions in a UPT creation dialog box. The following improvement and bug fixes have been made in the STAAD/Pro Graphical Interface I. General 1. Large input files were loading slowly. This problem has been rectified. 2. Labels were not being displayed properly. This has been corrected. 3. the "Print Preview" option was causing the program to crash when initiated from a new view with few members. This has been corrected. II. Pre-Processing 1. The Structure Wizard was not generating triangular meshes properly. This problem has been fixed. 2. A memory leak in the Structure Wizard which was causing the program to crash has been fixed. 3. Specifying the Member Orientation using a Reference Point would cause the program to hang. This has been corrected. III. Post-Processing 1. Errors in drawing stress contour diagrams have been resolved. 2. Values in the "Beam Relative Displacement Table" were displayed incorrectly. This has been corrected. ------------------------------------------------------------------------------ 8.2 STAAD Editor The Save As command has been removed from the Editor File menu when the editor is started from within the STAAD/Pro graphical user interface. ------------------------------------------------------------------------------ 8.3 STAAD Analysis The following items have been added to the STAAD Analysis engine. 1. New warning messages which are easier to understand have been implemented. 2. A new solver has been added to the STAAD engine to help trap the instability of a structure more efficiently. This is triggered by the command "SET SOLVER 2" in the input file. The following bugs have been fixed in the STAAD Analysis engine. 1. A bug related to analyzing inclined springs has been corrected. 2. The following bugs related to composite sections have been fixed: a. The moment of inertia about the minor axis was being computed incorrectly. b. The section force output reported by the graphical user interface was different from the values given in the output file. 3. The program was crashing due to invalid and/or missing data in the UPT and MEMBER LOAD sections of the input file. This has been rectified. 4. Bug related to the Columbian Seismic loads have been fixed. 5. If a temperature or strain load is applied to a member and there are many members and load cases in the model, the program may take considerable amout of time to calculate section forces and section displacements. The program has been modified to reduce this time required. 6. If two or more loadcases contain SUPPORT DISPLACEMENT LOAD, the results for all except the last of those loadcases may be erroneous. This has been corrected. 7. If a DEFINE command for load generation is specified after a primary load case, such as in the following example: LOAD 1 SELF Y -1 LOAD 2 JOINT LOAD 2 FX 10 DEFINE WIND LOAD TYPE 1 INTENSITY 0.1 0.15 HEIGHT 12 24 EXPOSURE 0.90 YRANGE 11 13 EXPOSURE 0.85 JOINT 17 20 22 LOAD 3 WIND LOAD IN X-DIRECTION WIND LOAD X 1.2 TYPE 1 The program will crash while performing the operation "Calculating Joint Displacements". A check has now been introduced to detect if this sort of erroneous data specification, report an error message, and terminate the run. 8. If there is an error in the input data for the DEFINE WIND LOAD command, or if the DEFINE WIND LOAD and the accompanying data are absent but are referred to in a load case as shown in this example, LOAD 1 WIND LOAD X 1.2 TYPE 1 the program would crash. The program has been changed to report proper error messages in the output file. 9. If the Wind intensity under the DEFINE WIND LOAD command is provided with a negative value, a crash would occur during the analysis. This has been corrected. 10. If the data under the DEFINE USER TABLE command is incomplete, as shown in the following example START USER TABLE TABLE 1 UNIT KIP INCHES END the program may crash during the analysis. This has been corrected. 11. When the DELETE JOINT command is specified, if the JOINT number of 1 or more joints in this list has the peculiar characteristic that there are no members or plate elements or solid elements in the structure with the same number as the joint, the program will fail to delete this joint. This problem has been rectified. 12. If the DELETE MEMBER command has been specified, and if the structure contains solid elements, the program may crash during the early stages of processing such as Processing Member/Element information, or Performing Band-width Reduction. This bug has been fixed. 13. If a load case contains seismic loads such as UBC, AIJ, IS1893 loads, etc., and if there are errors in the input parameters for DEFINE UBC LOAD, DEFINE AIJ LOAD, DEFINE 1893 LOAD, etc., the program is currently not equipped to handle errors in these data, and hence, proceeds with the analysis without any warnings. Consequently, the results of the analysis may be wrong. Checks have now been introduced to detect these errors. 14. If the UBC ACCIDENTAL LOAD command is specified, at each joint where a mass is present, an additional torsional moment needs to be computed and applied as per the relevant clauses in the UBC code. There was an error in this computation which has been corrected. 15. The section properties calculated by the program for composite members, namely, members whose properties are specified using the command syntax as shown, 5 TA CM W12X26 CT 3.0 FC 4.0 were incorrect. This has been fixed. 16. If the PRINT STATICS CHECK command is specified, and if any load case contains seismic loads such as UBC, AIJ, IS1893, etc., it may appear as though there is a lack of static equilibrium between the applied loads and support reactions for this load case. This is due to the fact that the values reported under the APPLIED LOAD SUMMARY for this load case do not include the additional loads that act on the structure as a result of conversion of the sesmic load into static equivalent loads. The effect of these additional loads however are evident in the TOTAL REACTION summary for this load case. The summary of equivalent static loads generated from the seismic forces will now be printed as a separate item for that load case. ------------------------------------------------------------------------------ 8.4 STARDYNE Advanced Analysis The following bugs have been fixed in the STARDYNE Advanced Analysis engine. 1. A bug related to floor load generation has been fixed. ------------------------------------------------------------------------------ 8.5 Design The following items have been added to STAAD/Pro's design facilities. 1. Revised LRFD parameters have been implemented. 2. MAIN and TMAIN paramets in the IS800 code now accept a value of "1" to bypass the L/R ratio check. 3. Danish, Finnish and Swedish design codes have been added. The following bugs have been fixed in STAAD/Pro's design facilities. 1. Errors in the following interfaces have been fixed: a. BEMAS b. Canadian Concrete Code c. Chinese Steel Code d. Norweigan Codes 2. In the Chinese Steel code, if a member fails in slenderness (due to KL/r exceeding the allowable limit) and the output is requested using the TRACK 0 or TRACK 1 option, the program may erroneously report that the condition of failure is Clause GBJ 5.4.3. This has been corrected. 3. This problem pertains to the following situation. A concrete beam of a long span is divided into several short segments for modeling purposes and some/all of those span lengths have a dimension that is approximately the same as the depth of the cross section. If a concrete beam design is performed on these segments using STAAD's ACI code, the program will fail to perform and instead report an error message that "DESIGN NOT PERFORMED SINCE LOCATION FOR SHEAR DESIGN IS PAST THE MID-POINT OF THE SEGMENT." This situation has now been rectified in the following manner. The program will perform a flexural design on these segments. However, it will not perform the design for shear and torsion. 4. This bug pertains to the following circumstance only. It affects the Canadian steel design code. a) The member being designed is a frame member. b) It is not declared to be a truss member. c) It has axial compressive load only. It does not have any bending moments or shear forces. The axial compressive capacity calculated for this member may be overestimated by the program. In reality, due to precision related errors, the capacity is calculated as though the member has an axial load and an extremely small bending moment. Hence, the design ratio may be erroneous. 5. Until now, if steel design per the AISC ASD code was performed on a T-shape, the actual bending tensile stress as well as the bending compressive stress about the major axis was computed using the smaller of the 2 section modulii. This approach though not exact, was considered conservative. From now on, the stresses will be calculated using the exact section modulus depending on which fiber is in tension and which is in compression. 6. In the Chinese steel code if member fails in slenderness, member properties were reported incorrectly. This is now rectified. 7. In the Chinese steel code, Clause 5.4.2-1 used to be checked for I shaped beams subjected to Axial compression as well as bending. Clauses 5.4.2-2 & 5.4.2-3 were not checked at all. From now on, Clause 5.4.2-1 will be checked for I shaped beams subjected to Axial compression only. If the beam is subjected to bending moment with or without axial compression, clauses 5.4.2-2 & 5.4.2-3 will be checked instead. 8. In design of beams for flexure, shear and torsion per the Indian concrete code IS456:1978 the following would occur. Until now, the determination of the worst load case for flexural design was based upon the longitudinal reinforcement requirement for flexural moment only. The longitudinal reinforcement requirement for torsion corresponding to this load case was then added to the reinforcement calculated for flexural moment resistance to arrive at the total longitudinal steel area to be provided. Let's assume that there are two load cases, L1 and L2, where bending moment and torsion are BM1, TOR1 for the first case and BM2 and TOR2 for the second case. STAAD picked load case L1 as being critical merely because BM1>BM2. A similar error was made in selecting the critical load case for stirrup area. In reality, the critical load case is the one which yields the highest total longitudinal steel area, that is, for flexure + torsion. This has now been implemented. In the above example, the program will now pick the critical load case as the one which yields the higher of S1 and S2, where S1 is the longitudinal steel for BM1 + TOR1, and S2 is the steel for BM2 + TOR2. The design for stirrup area has also been modified to follow this approach. 9. In design of members per all steel design codes the following will occur. If the SET Z UP command is used, and if the members fails in slenderness (KL/r exceeds allowable limits), some of the values reported in the design output will be incorrect. The KL/r values for Y and Z axis are 2 of those incorrect terms. This bug has been fixed in the AISC ASD code only. ============================================================================== 7. What's New in STAAD/Pro 3.1, Build 1002.US.REL, 1002.US.NET, 1002.US.CORP 7.1 Graphical Interface 7.2 Security 7.3 Stardyne Advanced Analysis 7.4 Design 7.5 Miscellaneous ------------------------------------------------------------------------------ 7.1 Graphical Interface The following items have been added to the STAAD/Pro Graphical Interface. 1. Quick Print option for printing tables is now available in both the pre and post processing modes. 2. All graphical interfaces for defining loads are now complete. These include Moving Load, Wind Load, Time History Load, etc. Area Loads, Moving Loads and Time Loads can not be viewed graphically, although they can be defined graphically. 7.2 Security The Sentry Hardlock problem that arose in STAAD/Pro 3.0 Build 1007.US.REL, where the hardware lock was not being found has been fixed. 7.3 Stardyne Advanced Analysis An error with the APPEND file program has been corrected. 7.4 Design The following Steel Design parameters have been added to STAAD/Pro. 1. Main has been added for LS800 2. Tmain has been added for LS800 3. Track has been added for BS5950 7.5 Miscellaneous The Print Support Reaction command has been modified to handle joint lists. The BEMAS program has been added to the German distribution of STAAD/Pro 3.1. ============================================================================== 6. What's New in STAAD/Pro 3.0, Build 1007.US.REL 6.1 Graphical Interface 6.2 Security 6.3 Stardyne Advanced Analysis ------------------------------------------------------------------------------ 6.1 Graphical Interface The following bugs have been fixed in the STAAD/Pro Graphical Interface. 1. When rotating or cutting sections from zoomed views, the views were being un-zoomed. This problem has been fixed. 2. Creating plates using Circular Repeat or Mirror commands was yielding incorrect nodes for the plates. This has been fixed. 3. Deflection diagram in Query were being drawn on the Opposite side. They were printing this way also. This has been corrected. 4. Failure Diagram in the Result menu in Post Processing Mode was permanently greyed-out. It is now available when the results are available. It interacts with the page control also. 5. Mode shape displacement in the Result menu in Post Processing Mode was permanently greyed-out. It is now available when the results are available. It interacts with the page control and Load and Result Property Page of Icon. 6. Aluminium Section display was displaying sections of other section types. This has been corrected. 7. Weld Parameter for Aluminium Design was showing option 1 and 2 instead of 0 and 1. These are fixed. The following items have been added to the STAAD/Pro Graphical Interface 1. Envelope is now available for Beam results. In Post Processing mode ENVELOPE will be listed in the Load Case drop down box. 2. Units have been added in the Query Property page. 3. Moving Load Definition through the Graphical Interface has been completed. 4. Time History Type Definition through the Graphical Interface has been implemented. 5. Break All is implemented under the Geometry menu. 6. Response Spectra can be defined through the Load Page. 7. UBC Loads may now be input through the graphical interface. 8. Pictures saved in a STAAD/Pro session may now be used for subsequent sessions. 9. A new Unit converted has been implemented. 10. A new STAAD/Pro Editor with on-line help has been implemented. 6.2 Security A new and enhanced security system is now available for STAAD/Pro. 6.3 Stardyne Advanced Analysis The Lanczos eigensolver has been slightly changed for the buckling solution. In those cases where the transformed tridiagonal eigenmatrix is not diagonally dominant, Stardyne will no longer stop with a message; but will continue on. This will have no effect on models that successfully ran buckling in the past. However, for most of the difficult buckling problems that were stopping prematurely, the Stardyne buckling will now complete the buckling calculations successfully. ---------------------------------------------------------------------------------------------- 5. What's New in STAAD/Pro 3.0, Build 1005 STAAD/Pro 3.0, Build 1005 incorporates enhancements over the previous Build 1004 release. The online documentation or the printed documentation do not contain the information about the latest changes in STAAD component of STAAD/Pro. Please review the following as well as the STAAD/Pro Release Report 3.0 for more information. Changes in STAAD/Pro 3.0, Build 1005 from Build 1004 ---------------------------------------------------------------------------- 5.1 Graphical Interface The following Bugs have ben fixed in the STAAD/Pro graphical interface. 1. In previous builds of STAAD/Pro, if you had cut a section of a structure, then performed a dynamic zoom on that structure, the zoom window would show the entire structure in isometric view and you would have to cut the section again in the zoom window. This problem has been resolved. 2. After cutting a section of a structure and adding members to the section using the Add Beam Cursor, beams were not always added at the correct elevation. This problem has been resolved. 3. After selecting members/elements then selectying "View Selected Objects Only" from the View Menu, Only selected objects appear in the view window as expected. After selecting "Cut Section" and then "Show All", the entire structure is displayed. However if you were to go back to the View menu, you would notice that "View Selected Objects Only" was still selected. This problem has been resolved. ---------------------------------------------------------------------------- 5.2 Norweigan Concrete Design New element design parameters have been introduced in the Norweigan Concrete code.

Support displacement load facility is now available 2. During translation, a box explaining the current stage of processing is displayed. This is meaningful for large files where it appears STAAD/Pro may not be responding in previous versions. 3. In previous versions of STAAD/Por, For constants, properties and loads, if the value is extremely small, some digits were likely to be truncated. This problem has now been rectified. 4. Discretization of a harmonic function for time history analysis is now based on twelve points instead of ten. 5. Inclined support, multilinear springs and spring support generation facilities are not currently available for STARDYNE. A message will be displayed from now onwards indicating this fact. ------------------------------------------------------------------------------- 4.2 STAAD/Pro Graphical Interface Following is a list of modifications to the STAAD/Pro Graphical Interface available in STAAD/Pro 3.0, Build 1004 1. Property names for T-shapes cut from a wide flange section are now displayed using an upper case "T" alongside the name of the wide flange section. 2. During a Multiple Structure chack, the progress of checking the structure is displayed in a dialog box. 3. The Query option can now be accessed through the Tools Menu by selecting the Member Query option. This option is available only if a member is currently selected. 4. The true orientation of a cross section could not be displayed if a reference point was defined for that member. This problem has been rectified. 5. For forcing values, the forcing functions were erroneously multiplied by the length or force factor for conversion from the input file units to the base units in the STAADPRO.INI file. This is now corrected. 6. For certain types of panel shapes, previous floor load generation might not yield the correct member and joint load values. This problem has been corrected. 7. Member force diagrams will no longer be plotted for load cases involving response spectrum and time history analysis. 8. The UNL parameter, which was missing in previous versions, is now available in the AISC Design Code Page. 9. Query Output is now available for concrete column design. 10. Error in member generation through the REPEAT command specified in the input file is now corrected. 11. The origin of a structure can be shifted using a new option called Move Origin in the Geometry Menu. ============================================================================== 3.
