摘　　要：钢筋混凝土短肢剪力墙结构是一种新型的中高层住宅结构体系,已有较多的工程应用,但是短肢剪力墙的抗震性能较差,如何提高短肢剪力墙的抗震性能是目前工程界十分关注的问题。本文提出了带暗支撑短肢剪力墙结构,通过1/2缩尺的墙肢截面高厚比分别为5.0、6.5、8.0的3个L形截面带暗支撑短肢剪力墙和3个L形截面普通短肢剪力墙模型抗震性能试验的对比研究,分析了L形截面短肢剪力墙的破坏特征、承载力、刚度及其衰减过程、延性及滞回特性。试验表明,带暗支撑L形截面短肢剪力墙比普通L形截面短肢剪力墙的抗震性能明显提高。RC short pier shear wall structure is a new type of mid-rise residential structure system and it has been applied in many constructions in China.However,its seismic performance is inferior,so a lot of attention has been paid to improve its seismic performance.In this paper,the short pier shear wall with concealed bracing is proposed.Based upon the experimental study on the seismic performance of three 1/2 scale L-shaped short pier walls with concealed bracings and three 1/2 scale general shear wall,the effects of concealed bracings on the failure phenomena,bearing capacity,stiffness and its degradation,ductility and hysteresis property of L-shaped short pier shear walls are discussed,the seismic performance of the L-shaped with concealed bracings are also compared with that of the general L-shaped short pier shear wall.Experiment results show that concealed bracings can greatly improve the seismic performance of L-shaped short pier shear wall.
