Seismic Design
(OP)
All,
I am having trouble here understanding seismic design. I'm a young engineer and haven't had much experience with this.
I have a two story steel framed building. The floor level is a rigid diaphragm (concrete on metal deck) ~15' AFF. The roof level is a flexible diaphragm (metal deck) that is another 15'. I have calculated the base shear for the structure, but am confused as to where to go from there. (I've done seismic design for a one story, and know the basic half the load to the top, half to the foundation.. that's a given) I am not sure now how to determine the load that is distributed to the floor, roof and foundation based on the types of diaphragms.
Any help would be great. I've been searching for example problems online and haven't found anything useful. If you have anything, I would appreciate it a lot.
Thanks!
