I have a curved steel girder bridge that has been modeled in LEAP Steel. The model successfully designs cross-frames and will show tensile/compressive forces in the design runs. However, when trying to create an Analysis report, for both Dead Load and Live Load, analysis results for the last 3 cross-frames are all omitted.
The bridge has 4 girders. Bay 1 has 13 cross frames (including end diaphragms), Bay 2 has 14, and Bay 3 has 14. There are 41 total. The report always will only show results for 38. The 6 end diaphragms are always reported, and based on the implied numbering, the furthest 3 upstation interior cross-frames in Bay 3 never report analysis results. The model has been rerun with various different cross-frame arrangements, and in all cases, the last 3 cross-frames will not report results.
Is this anything anyone else has run into? Is this indicative of those cross-frames being omitted from the actual analysis, or is there some issue where the report is simply being generated incorrectly?
Not that bad of a program, for simple beam analysis/configurations; can design/analyze for AASHTO LFD and LRFD up to edition 6. Known Program Limitations include: Only Line Girder Analyses (has been a while since I used it, but I doubt they added frame or system analyses, so don’t let the 3D picture fool you). I can’t remember how it handles floorbeams/cross braces. Limited to Steel MyIndigoCard Login
