摘    要:采用非线性有限元分析法,对反复荷载下的钢筋混凝土带竖缝剪力墙进行了计算分析,建立了反复加载混凝土应力-应变关系模型,模型中考虑了混凝土开裂后钢筋和混凝土之间滑移摩擦关系,根据计算结果对钢筋混凝土带竖缝剪力墙的结构性能和破坏机理作了分析,并与试验结果进行了对照,取得了较为一致的结果。

关 键 词:钢筋混凝土  剪力墙  非线性  有限元  反复载荷

Abstract:The behaviors of R.C. slit shear wall under cyclic loading is investigated by using nonlinear FE method in this paper.A constitutive model of hysteresis characteristics of reinforced concrete is proposed.The effect of bond between steel and concrete is considered in the model. From the numerical analysis, the load-deflection characteristics, crack patterns and failure mechanisms are investigated. The results of analysis and experiment are compared and show reasonably in agreement with each other.
Keywords:Nonlinear analysis  Shear wall  Structural control  Cyclic load
