【摘要】 本文提出了带暗支撑剪力墙,并将其与双功能剪力墙组合应用,通过6个1/3缩尺的低矮剪力墙模型的低周反复荷载试验,重点分析了不同设计型式剪力墙的承载力、刚度及其衰减过程、延性、耗能、滞回特性和破坏特征,给出了承载力计算方法,计算结果与实测值符合较好。加设暗支撑可明显改善低矮剪力墙的抗震性能。更多还原

【Abstract】 In this paper, the RC shear wall with concealed bracings is presented and used in combination with the double function shear wall. Through the cyclic loading tests on six 1/3 scale low rise shear wall models, this paper emphatically analyzes the bearing capacity, stiffness and its attenuation, ductility, energy dissipation, hysteresis property and failure phenomena of different types of shear walls. Then, the formulas for computing the bearing capacity of RC shear wall with concealed bracings are brought out. The results obtained from the formulas and those from experiment are in good agreement.The experiment shows that the concealed bracings are able to improve greatly the seismic behavior of low rise shear wall.更多还原
