[摘要] 填充墙对结构的动力特性及抗震性能有很大的影响，但由于填充墙与结构相互作用的复杂性，目前对于带填充墙结构在地震下的弹性及非线性地震反应的研究较少。利用非线性分析软件Perform-3D，基于纤维模型理论，采用等效剪切滑移失效模型和等效斜撑压缩失效模型来考虑框架结构填充墙的弹性及非线性行为，重点对含填充墙结构在小震、中震、大震下的非线性地震反应进行分析，以评价带填充墙结构在不同地震水准下的抗震性能以及填充墙对结构抗震性能影响的利弊与程度。结果表明布置合理的填充墙对结构在小震、中震、大震下的抗震性能起到不同程度的有利影响。

Abstract: Infill walls have a great effect on the dynamic property and seismic performance of the structure. 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.
