| 摘 要： | 本文通过1/3缩尺的3个钢筋混凝土带暗支撑中高剪力墙和1个普通中高剪力墙模型的抗震性能试验研究,探讨了不同暗支撑设计型式对剪力墙的承载力、刚度及其衰减过程、延性、耗能、滞回特性及破坏机制的影响,并与相应普通剪力墙的性能进行了比较,建立了承载力分析的模型与计算方法,计算结果与实测值符合较好。加设暗支撑可明显改善中高剪力墙的抗震性能。

| Abstract: | Based upon the experimental study on the seismic behavior of three 1/3 scale mid rise shear walls with concealed bracings and a usual one, the effects of different types of concealed bracings on the bearing capacity, stiffness and its attenuation, ductility, energy dissipation, hysteresis property and failure phenomena of shear wall are discussed. In this paper, the seismic behavior of the shear wall with concealed bracings are also compared with that of the usual shear wall. The mechanical models and the formulas of bearing capacity are established. The results obtained from the formulas and those from experiment are in good agreement. The experiment show that concealed bracings are able to improve greatly the seismic behavior of mid rise shear wall. |
