Seismic Response of Vertically Irregular Structures

Seismic response of four irregular reinforced concrete test structures is interpreted using static analysis methods. The four test structures were simplified models of multi‐story building frames comprising frames and framewall combinations. Discontinuities in the vertical plane of the structures were introduced by discontinuing the structural walls at various levels. It is found that standard limit analysis and static inelastic analysis provide good measures of strength and deformation characteristics under strong earthquake motions.
