Dear all,
I am working on determining the seismic forces acting on my multi-story frame and need to determine the center of rigidity at each level? Can someone please refer me to which readily available reference, or websites, to get these formulae? I also need to distribute the moment generated (into Fx or Fz on each of my supports) from this center of rigidity which may be offset (or different) from the center of mass. What is the best way to do this? Again, references to readily available and usable formulas would be appreciated.
Thanks.
