沿竖向耗能剪力墙滞回特性的计算方法

为了研究沿竖向耗能剪力墙的抗震能力，进行了这种剪力墙和普通实体墙的低周反复荷载试验，建立了剪力墙的剪力－剪切变形滞回模型和耗能装置的滞回模型，并利用多垂直杆元模型计算这两类剪力墙在反复荷载作用下的荷载－位移滞回曲线，计算曲线和试验曲线比较一致，表明了所采用的计算模型和滞回模型的正确性

Calculating Method for the Hysteretic Characteristics of Shear Walls Dissipating Energy along the Vertical Direction

In order to study the seismic behavior of the proposed shear walls dissipating energy along the vertical direction, the experiments of this type of shear walls and solid walls under cyclic loads were carried out, then the hysteresis models of shear force-shear deformation and energy dissipation devices are established. By using the multi-component-in-pallel model, the force-displacement hysteresis curves of the two type shear walls are calculated. The calculated curves agree well with the experimental ones, which proves that the proposed calculation model and the hysteresis models are accurate.
