【摘要】 双向单排配筋剪力墙适用于多层住宅结构。为了研究双向单排配筋混凝土高剪力墙的抗震性能及暗支撑在这种墙体中的作用,进行了4个高剪力墙的低周反复荷载试验研究,包括1个双向双排配筋混凝土高剪力墙,2个双向单排配筋混凝土高剪力墙,1个带暗支撑的双向单排配筋混凝土高剪力墙。较系统地分析了其承载力、刚度及其退化过程、延性、耗能、破坏机制和破坏特征等。试验表明,经过合理设计,这种双向单排配筋高剪力墙可以满足抗震要求。更多还原

【Abstract】 The high-rise RC shear wall with bi-directional single row of steel bars is applicable for multistory residence building.In order to know the seismic performance of this shear wall,experimental studies on specimens of four high-rise shear wall under a low-frequency quasi-static cyclic loading were carried out.A specimen was high-rise RC shear wall with bi-directional double row of steel bars,two specimens were high-rise RC shear walls with bi-directional single row of steel bars,and a specimen was high-rise RC shear wall with bi-directional single row of steel bars and concealed bracing.Based upon the experimental studies,load-carrying capacity,ductility and its stiffness,degradation,hysteretic behavior,energy dissipation and failure phenomena of each shear wall are contrastively analyzed,and the effects of concealed bracing on the seismic performance of this shear wall are discussed.The experiments show that the high-rise RC shear wall with single row of steel bars will be able to satisfy the requirements of seismic design for multistory residence building if rational design is carried out.更多还原
