［摘要］以一個(gè)8度區(qū)、98m高的框架-核心筒結(jié)構(gòu)為例，通過靜力非線性分析和動(dòng)力彈塑性時(shí)程分析，研究在水平荷載作用下墻體出現(xiàn)受拉情況后，結(jié)構(gòu)抗震性能的變化和破壞模式的發(fā)展。結(jié)果表明，墻體受拉后，抗側(cè)剛度快速下降，內(nèi)力發(fā)生重分布，受拉、受壓墻肢承擔(dān)的內(nèi)力差異增大；受壓側(cè)墻肢承擔(dān)了主要內(nèi)力，結(jié)構(gòu)最終因首層受壓側(cè)墻肢壓彎承載力不足、無法繼續(xù)抵抗外力而破壞。

Abstract:The seismic performance variety and failure mechanism development of a 8 degree zone and 98m height frame-core wall structure were studied through static and dynamic nonlinear analysis methods, when shear wall may be in tensile state after resisting the horizontal loads. The results show that when shear wall under tensile condition, the lateral stiffness of core wall would degrade rapidly and the internal forces would redistribute. The difference of internal force between the tensile wall and the compression wall would increase. The compression wall bears main forces. Because of the insufficient flexural capacity of the compression wall, the structure wouldn′t resist external forces any more and would be destroyed.

Keywords:frame-core wall structure; nonlinear static procedure; dynamic nonlinear analysis; shear wall under tensile condition; compression failure
