摘　　要：轻钢泡沫混凝土剪力墙是一种新型节能建筑结构,具有轻质高强、抗震性能好和绿色环保等优点。为深入研究和分析轻钢泡沫混凝土剪力墙的抗震性能,利用ABAQUS软件对其建立有限元模型,对不同轴压比的轻钢泡沫混凝土剪力墙进行非线性分析,考察不同轴压比下轻钢泡沫混凝土剪力墙的承载能力及变形能力的变化。有限元分析表明:在规范给定的剪力墙轴压比限值内,随着轴压比在一定范围内的增大,轻钢泡沫混凝土墙体的损伤区域逐渐向上扩展,墙体的承载能力增强,变形能力下降。Lightweight steel-foam concrete shear wall is a new energy saving building structure,which possesses a great many of positive features such as light weight and high strength,aseismatic performance,environmentally friendly and so on. In order to study the seismic behavior of the lightweight steel-foam concrete shear wall,the finite element moodel is establishecl by ABAQUS software,and nonlinear analysis of the wall with different axial compression ratio is carried out,in order to investigate the variation of bearing capacity and deformation capacity of lightweight steel-foam concrete shear wall. Through finite element analysis and calculation,the following conclusions are obtained: within the limit value of axial compression ratio shear wall in JGJ3-2010,as the axial compression ratio increases within limits,the damage zone of the specimens expands gradually,the load-bearing capacity of the specimens increases,but the deformation capacity shows an opposite trend.
