Release Notes for RISA-3D 7.1.3

Descargar

Misc. Corrections

• Corrected a bug that could result in a crash while using the embedded version of RISAFoot 3.0. The problem only occurred when one of the Load Combinations used for footing design included an AISC 13th Edition code check with the “adjust stiffness” option of the Direct Analysis method.
• Corrected a serious bug that could result in the deleting of embedded RISAFoundation data. If a RISA-3D file with embedded RISAFoundation were saved without having first viewed the Footing data during that session, then the Foundation information would NOT be embedded in the 3D file.
• Corrected a bug related to the validation of RISAFoot version 3.0 licensing. Previously the network version of RISAFoot was not correctly authorizing.
• Corrected a 2nd bug related to RISAFoot authorization that related to launching RISA-3D from within a RISAFloor session.
• Corrected a bug related to the reading of the results file. There were instances where saved results were being discarded even when they were present and valid.
• Corrected a crash on the re-use of eigen solution results for the accelerated dynamic solver.
• Corrected a bug with the optimization of concrete reinforcement. The bug would have prevented the program from adding steel that is above the min flexural steel requirements.
• Corrected a Steel Database error in AISCDB32.FIL associated with HSS6.625x0.375.

Misc. Corrections

• Corrected a bug where the use of the Automatic Response Spectra Scaling Factor in a solution could cause a crash.
• Corrected a bug in the single angle code that did not allow for single angles to bend about their Geometric axes even when this was specifically requested by the user.

• Log of members that had invalid or missing design lists

• Corrected an error with reading default program settings created by an older version (pre-7.0)
• Corrected bug where Plates spreadsheet would not open properly from the Main Menu toolbar.
• Corrected bug in the truss generator that mis-calculated chord centroids when the ‘Maintain Out-to-Out’ distance was selected
• Added code to prevent infinite iteration issues for footings and One-Way elements.
• Added dialog to calculate detailing offsets for CIS/2 translator.

• Corrected a 2nd bug related to RISAFoot authorization that related to launching RISA-3D from within a RISAFloor session.
• Corrected a bug associated with the Beam to Beam drawing behavior using 2nd beam offsets. 3.2 and 3.2.1 were creating a joint at the correct locations, but were not connecting the new beam to those nodes.
• Corrected a bug associated with the Self Weight of Lateral walls that were brought into RISAFoundation. Essentially the self weight of the wall was being included twice.
• Corrected a bug associated with the saving and retrieving of drawing grids.
• Corrected a bug with the optimization of concrete reinforcement. The bug would have prevented the program from adding steel that is above the min flexural steel requirements.
• Corrected a Steel Database error in AISCDB32.FIL associated with HSS6.625x0.375.
• Corrected a bug where RISA-3D could not design footings if the program were initiated from RISAFloor through the Director menu.
