Design report

For the analysis report of the attached model, if you look at Tabl 1523_I cell H75(before composite) and compare it with Cell 177(after composite). Why does the demand decreases in after composite case (7885.14)?

Thanks,

Hi,

This is happening because the governing load combinations are different between before composite and after composite. The governing load combinations are LCB 8 and LCB 1 for 'before composite' and 'after composite', respectively.
