开洞钢板再生混凝土剪力墙抗震性能模拟分析

Simulation Analysis of Seismic Performance of Reclaimed Concrete Shear Wall with Perforated Steel Plate

通过数值模拟方式对6片开洞钢板再生混凝土剪力墙进行了建模分析。对构件施加低周往复荷载,分析孔洞率、孔洞形状和孔洞位置等参数对剪力墙滞回性能和耗能能力的影响。结果表明:孔洞率对钢板再生混凝土剪力墙的滞回性能和耗能能力影响最大;孔洞形状对抗震性能影响较显著;孔洞位置对剪力墙抗震性能的影响最小。

Through the numerical simulation method, the modeling analysis of six perforated steel plate reclaimed concrete shear walls was carried out.Low cyclic load is applied to the components, and the influences of parameters such as cavity rate, cavity shape and cavity location on hysteretic performance and energy dissipation capacity of shear walls are analyzed.The results show that the porosity has the greatest influence on the hysteretic properties and energy dissipation capacity of the recycled concrete shear wall.The shape of the hole has a significant effect on the seismic performance.The location of holes has the least influence on the seismic performance of shear walls.
