Load Combination Generator - User Defined Wind Load
I am trying to use the load combination generator but it is not generating load combinations with user defined wind load cases and notional loads. If I turn notional loads off or toggle to include them only with gravity loads the generator includes wind…
RE: RAM Semi-Rigid Diaphragm Deflected Shape
If it's only for Dynamic Response Spectrum analysis, it's probably a localized sign reversal. You can confirm by checking the forces in the column. More here:

RE: Semi-Ridged Diaphragm With Sloped Roofs (Gables)
The diaphragm forces were always calculated for sloping semirigid diaphragms. However, the way that the loads are applied can cause unintended behavior and lead to odd results. See the frequently asked question, " How do sloping semirigid diaphragms affect…
