Center of rigidity
(OP)
When calculation the torsional moment on a structure, is the center of rigidity calculated the same way for multi-story buildings compared to single story buildings.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

For a two story building I don't see a problem with calculating the C.R. at each level.

1) Lateral force resisting system is signicantly different from one level to another.
2) Stiffness of the system (due to brace size, story height, or thickness or nailing of shear wall) varies significantly from one floor to another.
3) A floor where this is a discontinuity in the lateral force resisting system.... i.e. a braced frame or shear wall terminates and that force has to be dragged through a collector element or diaphragm to another lateral frame or wall.
