Abstract: “In this paper, the development of a spectrum-based nonlinear dynamic analysis, named as incremental substitution procedure (ISP), is presented for the seismic vulnerability assessment of tall buildings. The proposed procedure is derived from a special case of nonlinear time-history analysis, where the seismic responses of a structure can be captured from a series of equivalent linear systems and ordinary response spectra. Case studies are conducted and the results show very good agreement with the field observations. Conclusions are drawn and recommendations are made for the reconstruction work of earthquake-stricken areas and the vulnerability assessment of buildings in the nearby regions.”
