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,并以典型的双肢短肢剪力墙为例,选择了4个1/3缩尺的双肢短肢剪力墙试验模型,2个为普通双肢短肢剪力墙模型,2个为带暗支撑双肢剪力墙模型,进行了对比性的抗震性能试验研究,较系统地分析了带暗支撑双肢短肢剪力墙的承载力、刚度、延性、耗能能力及破坏特征,建立了承载力计算模型,计算结果与实测结果符合较好。试验表明,带暗支撑双肢短肢剪力墙的抗震能力比普通双肢短肢剪力墙显著提高。RC short-pier shear wall structure is a new type of mid-rise residential structure system. It has been applied in many buildings. Because its seismic performance is worse, improving its seismic performance becomes a problem, which attracts the attention of engineers. In this paper, the short-pier shear wall with concealed bracings is proposed, and contrastive seismic performance experiment study is carried out. In this study, four 1/3 scale cou, pled short-pier shear wall specimens are designed, two of which are general coupled short-pier shear wall, and the others are coupled short-pier shear wall with concealed bracings. The bearing capacity, stiffness, ductility, energy dissipation and failure phenomena of shear wall with concealed bracings are systematically analyzed. Based on the experiment research, the mechanical models for calculating bearing capacity of the short-pier shear wall with concealed bracings are established, and the calculated results well agree with the measured ones. The experiments show that the seismic performance of short-pier shear wall with concealed bracings is greatly improved.
