Nonlinear seismic response analysis of RC structural walls based on pattern of self - equilibrating stresses

本文简要评述了现有钢筋混凝土剪力墙的非线性分析模型，着重介绍了多竖线单元模型，并对其竖向单元的轴向刚度和水平弹簧的剪切刚度分别建议了改进的滞变模型。最后将基于自平衡力的非线性动力反应分析方法应用于求解剪力墙结构的非线性地震反应，并用传统分析方法对其结果进行了检验，表明该分析方法计算简便，而且是有效和可靠的。

Nonlinear analytical models of RC structrual wall are summarized in this paper. The multi ple-vertical-line-element model is introduced in detail and the improved hysteretic models for its axial stiffness of vertical element and shear stiffness of horizontal spring are recommended respectively. Finally, the method of nonlinear dynamic analysis based on pattern of self-equilibrating stresses is applied to solving nonlinear seismic response of RC shear wall structures. The calculational results of an application example are verified by using classical method. It is shown that this method is effective and reliable and it has advantage of simple calculation.
