摘要:
在低周反复荷载下,对4个叠合板式剪力墙和2个普通剪力墙进行对比试验,系统分析试件的刚度退化趋势.基于理论公式及试验数据,建立往复荷载作用下构件的三折线型恢复力模型,与试验结果较为吻合.基于小波变换原理,提出一种新的基于小波变换的恢复力模型特征参数的计算方法.该方法简便,可较好地反映试件在各阶段刚度的变化,更符合刚度退化的实际情况.
Abstract:
Under low cyclic loading,comparative experimental study on four superimposed slab shear walls and two general shear walls is conducted.The stiffness degeneration of the specimens is analyzed systematically.Based on the theoretic formulas and testing data,the trilinear restoring model under low cyclic load is established.which agrees well with the test results.Based on wavelet transform,a new calculation method about character parameter of the restoring force model is also presented.This concise method could reflect the stiffness change of the specimens at different stages,and also agrees well with the experimental phenomenon of stiffness degeneration.
