为了解斜筋布置形式对单排配筋混凝土中高剪力墙抗震性能的影响,进行了4个带斜筋和1个不带斜筋的单排配筋混凝土中高剪力墙低周反复荷载试验,对比分析了各剪力墙的破坏形态、滞回性能、承载力、延性、刚度退化和耗能能力,研究了斜筋角度和配筋比例对中高剪力墙抗震性能的影响.结果表明：对于低配筋量的单排配筋混凝土中高剪力墙,墙体分布钢筋的配置形式变化对其破坏形态、极限承载力和延性影响不大;配置斜筋可在一定程度上减小墙体剪切滑移变形,斜筋呈扇形布置对于减小墙体剪切滑移变形效果相对较好;与不配置斜筋的单排配筋混凝土中高剪力墙相比,配置斜筋的单排配筋混凝土中高剪力墙后期刚度衰减速度相对较慢,抗震耗能能力较好.

英文摘要：

In order to study the effect of inclined reinforcement arrangement on seismic behavior of mid-rise RC shear wall with single row of steel bars,the low cyclic loading tests for four mid-rise RC shear walls with single row of steel bars and inclined reinforcement and one without inclined reinforcement were carried out respectively. The failure mode,hysteretic behavior, load-carrying capacity, ductility,rig id ity degeneration and energy dissipation capacity of five test specimens were contrastively analyzed. The influences of intersection angle between inclined reinforcement and horizontal direction as well as the proportion of web reinforcement and inclined reinforcement on the seismic performance of mid-rise RC shear walls were also revealed. The test results indicate that different reinforcement arrangements have little influence on failure mode,ultimate load-carrying capacity and ductility for the mid-rise RC shear wall with single row of steel bars,but the inclined reinforcement can reduce shear slipping of the wall to a certain extent,and the inclined reinforcement positioned as fan-shape is more effective. The mid-rise RC shear walls with single row of steel bars and inclined reinforcement show slower stiffness attenuation and better energy dissipation capacity than that of the shear wall without inclined reinforcement.
