[摘要] 填充墻對(duì)結(jié)構(gòu)的動(dòng)力特性及抗震性能有很大的影響，但由于填充墻與結(jié)構(gòu)相互作用的復(fù)雜性，目前對(duì)于帶填充墻結(jié)構(gòu)在地震下的彈性及非線性地震反應(yīng)的研究較少。利用非線性分析軟件Perform-3D，基于纖維模型理論，采用等效剪切滑移失效模型和等效斜撐壓縮失效模型來考慮框架結(jié)構(gòu)填充墻的彈性及非線性行為，重點(diǎn)對(duì)含填充墻結(jié)構(gòu)在小震、中震、大震下的非線性地震反應(yīng)進(jìn)行分析，以評(píng)價(jià)帶填充墻結(jié)構(gòu)在不同地震水準(zhǔn)下的抗震性能以及填充墻對(duì)結(jié)構(gòu)抗震性能影響的利弊與程度。結(jié)果表明布置合理的填充墻對(duì)結(jié)構(gòu)在小震、中震、大震下的抗震性能起到不同程度的有利影響。

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.
