I am hoping to use STAAD for beam design for a run of simple span beams with dead and live loads. I currently can not get the program to stop designing for deflection based on factored loads. I was strength design based on envelope 2 and deflections…

I know when I input seismic UBC/IBC seismic loads I should type Perform Analysis and Change after each load case. The problem is, I am using National Building Code of Canada to generate seismic loads in my model and STAAD Pro still gives me the warning…
