PREDICTION OF SEISMIC RESPONSE OF MULTI-STORY UNSYMMETRIC FRAME BUILDINGS

Abstract

A nonlinear static procedure for multi-story unsymmetric frame 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 an estimation of the nonlinear response of equivalent SDOF model. The predicted results are compared with the nonlinear dynamic analysis results, and satisfactory predictions can be obtained by the proposed procedure.
