| 摘 要： | 为了研究密肋复合墙板的恢复力模型特性,对9块模型墙板进行了周期反复荷载作用下受力性能的研究,介绍了墙板的破坏过程及滞回曲线的特点,根据骨架曲线以及刚度退化的分析,并利用反向加载时曲线指向最大值的规律,建立了复合墙的四线形恢复力模型,通过试验拟合及理论分析提出了骨架曲线中各特征参数点的计算方法,试验值与计算值吻合较好,说明该恢复力模型能够反应密肋复合曲线墙开裂-屈服-破坏的全过程,为密肋复合墙体结构进行弹塑性时程分析提供了依据.

| Abstract: | In order to study the restoring force model of multi-ribbed composite wall,Pseudo-static tests of 9 samples had been carried out under cyclic lateral loading, and the failure process and failure characteristics are summarized in details. By analysis of skeleton curve and stiffness degradation, four linear restoring force model of the multi-ribbed composite wall has been established according the rule that the curve points to the maximum value as reverse loading. The calculation of the main parameters of the skeleton curve are given by tests and theoretical analysis, and the values of the calculation are consistent of that of the tests. The restoring force model reflects the failure process of the multi-ribbed composite wall as crack-yield-failure,which provide basis for elastic-plastic time-history analysis of multi -ribbed composite wall structure. |
