［摘要］為了研究短肢剪力墻的抗震性能，對(duì)6個(gè)1/2比例的T形短肢剪力墻試件進(jìn)行了低周反復(fù)荷載作用下的試驗(yàn)研究，分析了短肢剪力墻的承載力、延性、滯回特性、耗能能力及破壞機(jī)制等抗震性能。結(jié)果表明：短肢剪力墻試件以彎剪破壞為主，截面高厚比較大試件的腹板中部易發(fā)生剪切破壞；腹板底部是試件最薄弱部位，加暗支撐可明顯增加試件的延性和極限承載力；隨著試件軸壓比的提高，試件延性降低，極限承載力增加。

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.

Keywords:short pier shear wall; quasi-static test; seismic performance; experimental research
