I went with moment frames across the 45' span and this controls the deflection. The bay spacing is about 18' on center by the way. Without moment frames and just bracing at the end walls the model was unstable which spurred the "need" for springs to get it to behave. I believe I had the wrong...
Hello,
I am a long time reader but first time poster. I have an issue that has myself and a few others a little stumped. I have built a model in RISA Floor which I analyzed then moved to 3D for lateral analysis. Understanding flexible diaphragms are not well modeled, I was following the...
