A simplified nonlinear analysis procedure to oredict earthquake responses of multi-story asvmmetric buildings is presented and some examples are shown in this paper. In this procedure. their responses are predicted through a nonlinear static analysis of MDOF model and estimation of seismic demand of equivalent SDOF model, considering the change in the first mode shape at each nonlinear stage and the effect of the first and second mode contribution. The results show that the responses of multi-story asymmetric buildings can be satisfactorily predicted by the proposed procedure.
