A nonlinear static procedure for single-story unsymmetric buildings subjected to bi-directional excitation is presented and its applicability is discussed. In this procedure, their responses are predicted through a pushover analysis of MDOF model considering the effect of bi-directional excitations and a estimation of the nonlinear response of equivalent SDOF model. The predicted results are compared with the nonlinear dynamic analysis results, and it is shown that the equivalent modal mass ratios of the first and second modes are the indices to discuss the applicability of the presented procedure.
