将多层住宅剪力墙中的一部分钢筋布置成斜向钢筋,可改善单排配筋剪力墙的结构性能,增强其抗剪切性能,提高其抗震能力。为研究此种配筋方式的L形截面剪力墙抗震性能,分别对单排配筋混凝土L形截面剪力墙模型和带斜筋的单排配筋混凝土L形截面剪力墙模型进行低周反复荷载试验,对比分析两者的承载力、延性、刚度、滞回特性、耗能能力及破坏特征,研究斜筋对改善单排配筋L形截面剪力墙抗震性能的效果。结果表明,合理布置斜筋可以显著提高单排配筋L形截面混凝土剪力墙的承载力、延性和耗能能力,使其能更好地满足多层住宅结构的抗震要求。
Laying a part of reinforced bars in multi-story residential shear walls into diagonal bars can improve the structural performance of single-row reinforced shear walls, enhance their anti-shear performance and improve their anti-seismic capacity. In order to study the seismic behavior of the L-section shear wall reinforced by this kind of reinforcement method, the L-section shear wall model with single row of reinforced concrete and the single-row reinforced concrete L-section shear wall with oblique bars Week repeated load test, the bearing capacity, ductility, stiffness, hysteretic characteristics, energy dissipation capacity and failure characteristics of the two are compared and analyzed. The effect of oblique reinforcement on the seismic performance of single-row reinforced L-section shear wall is studied. The results show that the rational arrangement of diagonal bars can significantly improve the bearing capacity, ductility and energy dissipation capacity of L - section concrete shear walls with single row of reinforcement so that it can better meet the seismic requirements of multi - storey residential structures.
