摘　　要：通过3片复合剪力墙的1/2比例模型试验,研究复合剪力墙在偏心荷载作用下内外两片混凝土层协调工作能力、复合墙板工作稳定性、裂缝发展特征;采用有限元分析软件构建轴心受压构件有限元模型,对构件极限承载力模拟值与试验值进行对比分析,两者误差在可接受范围,验证了模型的可靠性。基于有限元分析结果,针对性提出复合剪力墙偏心受压正截面承载力计算公式,可供设计参考。Based on test of three 1/2-scale model specimens of composite shear wall,the paper studies the coordinated working ability of two concrete layers inside and outside the composite shear wall under eccentric load,as well as the stability of the composite wall panel and the development characteristics of cracks.The finite element model of axial compression member is constructed by finite element analysis software,and the simulated and experimental values of the limit bearing capacity of the member are compared and analyzed.The error of both is within an acceptable range,which verifies the reliability of the model.Based on the finite element analysis results,a formula is presented for calculating the bearing capacity of normal section under eccentric compression of composite shear wall,which can be used as reference for design.
