摘　　要：本文对6片1/2几何缩尺比例的T型短肢剪力墙构件进行了低周反复荷载试验,通过HRB500E高强钢筋与C50高强混凝土的组合应用,并变换设计轴压比以及截面高厚比等相关参数形成对照试验组。探究了T型短肢剪力墙的破坏模式与恢复力模型,同时研究了相关参数的变换和高强度材料的使用对构件延性的影响,并对试验结果进行了非线性有限元仿真分析下的对比论证。In this paper,6slices T-shaped short leg shear walls components with1/2geometric scale models are tested under low cyclic loading.Through the combined application of HRB500E high-strength steel bar and C50high-strength concrete,and the relevant parameters such as axial compression ratio and section thickness ratio are transformed into design control test group.The failure mode and restoring force model of T-shaped short pier shear wall are explored.Meanwhile,the influence of transformation of relevant parameters and the use of high strength materials on ductility of components is studied.
