［摘要］为了研究短肢剪力墙的抗震性能，对6个1/2比例的T形短肢剪力墙试件进行了低周反复荷载作用下的试验研究，分析了短肢剪力墙的承载力、延性、滞回特性、耗能能力及破坏机制等抗震性能。结果表明：短肢剪力墙试件以弯剪破坏为主，截面高厚比较大试件的腹板中部易发生剪切破坏；腹板底部是试件最薄弱部位，加暗支撑可明显增加试件的延性和极限承载力；随着试件轴压比的提高，试件延性降低，极限承载力增加。

Abstract:To explore seismic performance of the short pier shear wall, the experiment of six 1:2 scale T-shaped short pier shear walls subjected to low cyclic loading were conducted. The bearing capacity, ductility, hysteretic characteristics, energy dissipation capacity and failure mechanism of the short pier shear wall were investigated. The results show that specimens mainly present bending-shear failure modes, and shear failure is easy to appear in the middle of webs in those specimens with big sectional depth-thickness ratio. The bottom of web is the weakest part of the specimen. The ductility and the ultimate bearing capacity of the specimens can be obviously increased by adding concealing bracings to the web. The ductility of the specimens is decreased and the ultimate bearing capacity is increased by raising axial compression ratio.
