摘要

为了研究不同肢厚比对框支短肢剪力墙斜柱式转换层结构抗震性能的影响,对3榀框支短肢剪力墙斜柱式转换试件进行了竖向荷载和水平低周反复荷载共同作用下的拟静力试验,分析了试件的破坏过程及特征、承载力、滞回及耗能特征、刚度退化和位移延性。试验结果表明,斜柱式转换层结构的受力特点近似于一个简单的桁架,转换层上部短肢剪力墙肢厚比对转换梁的性能有重要影响,设计合理的框支短肢剪力墙斜柱式转换层结构具有较好的延性,可形成多道抗震防线,从而获得较好的抗震性能。

Abstract

Three inclined column-shaped transfer floor structures of frame-supported short-leg shearwall are tested under vertical loading and horizontal cyclic loading to analyze the influence of leg-thickness ratio on the seismic performance of inclined column-shaped transfer floors. The failure process and patters, bearing capacity, hysteretic characteristics, stiffness degradation, deformation and ductility are analyzed in detail. The test results show that the force characteristic of inclined column-shaped transfer floor structure is similar to a simple truss, and leg-thickness ratio of the top short-leg shearwall has important implications to the transfer beam performance; if the design is reasonable, the inclined column-shaped transfer floor structure has a good ductility, multi-channel seismic line of defense and better seismic performance.
