pushover analysis using sap2000

(OP)
i have modelled 3 types of building in sap2000 that is
G+3,G+4, and G+5. i am getting the pushover curve in
which
roof displacement is increases from G+3 to G+5 but base
shear is decreasing. is it ok or is there anything i am
missing?
please help me.

RE: pushover analysis using sap2000

Hi,

Do you building have identical configuration in plan?
Check the seismic mass definitions,Loads on the structure.
Height and stiffness of the building greatly influence roof displacement. Base shear is mainly influenced by seismic weight of the building.

Best,
