I would like to know how staad calculate story stiffness?
I am using FLOOR DIAPHRAGM and PRINT STORY STIFFNESS to get story stiffness from staad.
Now suppose structure with 5 floor and same height. All column and beam are of same size. When I check story stiffness result why they differ floor to floor when all floor are similar?
Kindly reply.

PN
