pushover of plan-irregular buildings

Post by mattia86 »

I have an irregular structure in plan and I do pushover analysis. What is the correct way to proceed:
-Plug for each field slab rigid links (constraints x + y + rz) and connect to the 4 corner nodes by applying lateral forces in the center of gravity of the masses.
-Connect the center of gravity of the masses with all the corner nodes of the structure in the plan and apply forces in the center of gravity of the masses.

p.s.exclude rigid diaphragms because I have problems of convergence
Many thanks
