A simplified nonlinear analysis procedure to predict earthquake responses of single-story asymmetric buildings is presented and its applicability is discussed. In this procedure, their responses are predicted through a nonlinear static analysis of MDOF model and a nonlinear dynamic analysis 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 torsionally stiff buildings can be satisfactorily predicted by the proposed procedure.
