In a RAM SS model, I tried assigning HSS2.5x2.5X1/4 beam size to a beam. This size is available in the "Assign Size" dialogue box.
However, when I run the design, the following error message is generated and the user assigned size is cleared. Is there a way I can incorporate these sizes into the design? Any help is much appreciated! Thanks in advance!
You will need to edit the .bms table. See: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/3113/ram-table-editing-faq
