【摘要】：在低配筋量的单排配筋混凝土低矮剪力墙中配置斜向钢筋,可限制基底施工缝处水平剪切滑移和墙体斜裂缝开展,提高混凝土低矮剪力墙的抗震耗能能力.为探求带斜筋单排配筋混凝土低矮剪力墙的优化配筋设计方法,进行了5个不同配筋设计的剪力墙模型低周反复荷载试验,对比分析了各模型的破坏特征、滞回性能、承载与变形能力、刚度退化规律、耗能能力及钢筋应变发展规律.试验结果表明:对于单排配筋混凝土低矮剪力墙,斜筋可有效控制其剪切变形,使其抗震性能优于不带斜筋的剪力墙;合理配置斜筋,可明显提高混凝土低矮剪力墙的抗震耗能能力,获得性价比较高的抗震墙.
[Abstract]:In the low shear wall of single row reinforced concrete with low reinforcement the horizontal shear slip at the base construction joint and the inclined crack of the wall can be restricted and the seismic energy dissipation ability of the concrete low shear wall can be improved. In order to explore the optimal reinforcement design method of single row reinforced concrete shear wall with inclined reinforcement, five shear wall models with different reinforcement designs were tested under low cycle repeated load, and the failure characteristics and hysteretic performance of each model were compared and analyzed. Bearing capacity and deformation capacity, stiffness degradation law, energy dissipation capacity and strain development law of steel bar. The test results show that for single row reinforced concrete low shear wall, inclined reinforcement can effectively control its shear deformation and make its seismic performance superior to that of shear wall without inclined reinforcement. The seismic energy dissipation ability of low concrete shear wall can be improved obviously, and the high performance and price ratio seismic wall can be obtained.
