Josh - I'm curious if RISA products have made any improvements/changes in their semi-rigid diaphragm analysis since your last response? TIA!

Well, RISAFloor now has a "semi-rigid" diaphragm definition. But, that just means that you can set a thickness and material of the diaphragm. The same as you always could in RISA-3D.

The only differences is that now the RISAFloor / RISA-3D combination will automatically mesh your diaphragm and will generate standards wind and seismic loading for it. Those aspects are not available in RISA-3D by itself.
