考虑截面形状及钢筋阻滞作用的挡水建筑物剪力墙隔震设计

摘要

以截面形状替代原始形状,结合钢筋阻滞作用的挡水建筑物剪力墙隔震设计,弥补了原有墙体承载力、刚度及其延性、耗能、滞回特性的不足.为确定截面形状钢筋阻滞作用下的剪力墙隔震设计的有效性,进行了挡水建筑物剪力墙开裂破坏试验,结果表明截面形状及钢筋阻滞作用的挡水建筑物剪力墙的隔震性能明显优于原始形状的剪力墙设计,钢筋阻滞作用明显增强,承载力和延性效果显著.%Reducing forces on cross section shape and reinforced block wall isolation design consideration,based on the original shape and reinforced under the action of force wall design of deformation and energy dissipation capacity is low,the design pattern of shear wall bearing capacity,stiffness and ductility,energy dissipation,hysteresis property.the influence of reinforced block and isolation performance is not ideal.For this,put forward to cross section shape instead of the original shape,reducing forces on reinforced block wall isolation design,through the study,cross section shape is established and the calculation method of reinforced block effect,and the experimental results show that the cross section shape and reduction of forces on reinforced block wall isolation design of vibration isolation performance is superior to the original shape and reinforced under the action of force wall reduction design of reinforced block is enhanced obviously,bearing capacity and ductility.
