Mass matrix

Post by amarnath »

Hi
I am modeling 3d building, each floor is modeled using rigidDiaphragm. Nodes of a particular story is constrained to a master node at that story , using rigidDiaphragm. If I define mz and mx mass for all the story nodes instead of defining mx,mz,Iy for the master node will Opensees automatically calculate the Iy component of mass matrix of the structure, from nodal mx and mz values?
