For the complexity of the interaction between infill wall and structure, there are fewer researches on the elastic and nonlinear seismic response of the infll wall structure. In order to evaluate the seismic performance of infill structure and the effect of infll wall forced on structures, this research uses fiber model theory, adopts equivalent sliding shear failure and compression failure of diagonal struts models to consider the nonlinear behavior of infill walls, gives a research on the seismic performance of the infill frame under small minor, moderate and major earthquake. The result indicates that the infll walls can have a different good effect on the infill structures at different eaIthquake levels if the infill walls are arranged reasonably.Keywords: infll wall; seisnuc performance;Perform-3D;nonhnear
