摘要

CFST边框内藏桁架剪力墙是一种新型组合剪力墙。为研究其抗震性能和抗震机理，本文进行了3个1/5缩尺高剪力墙的低周反复荷载试验。在试验研究基础上，分析了该新型组合剪力墙的承载力、延性、刚度及其衰减过程、滞回特性、耗能能力及破坏特征，通过ABAQUS有限元软件进行了弹塑性有限元分析。研究表明：CFST边框内藏桁架剪力墙具有良好的抗震屈服机制，抗震性能比普通混凝土剪力墙显著提高。

Abstract

Shear wall with CFST columns and concealed trusses is a new kind of shear wall. In order to research its seismic performance and seismic mechanism, experiments were studied on three 1/5 scale high shear wall models. Based on the experimental research, load-carrying capacity, ductility, stiffness and its attenuation, hysteretic property, energy dissipation and failure phenomena of each model were analyzed. The finite element analysis was done through ABAQUS. The research show that shear wall with CFST columns and concealed trusses has good seismic yielding mechanism, and the seismic performance are obviously increased compare to normal RC shear wall.
