| Abstract: | Modal pushover analysis (MPA) is an improved pushover analysis procedure based on structural dynamics theory.It not only retains the conceptual simplicity and computational effectiveness of the procedure with invariant force distribution,but also provides superior accuracy in estimating seismic damage on buildings.On the basic of MPA procedure,combined with the approach proposed by A.Ghobarah for the assessment of the damage index for multi-story buildings by using results of twice pushover analyses,a modal damage index is proposed in this paper. |
