摘　　要：为研究轻钢-泡沫混凝土组合墙体的力学性能,采用ABAQUS有限元软件开展三个轻钢-泡沫混凝土组合墙体试件偏心受压仿真分析,三个试件的含钢率依次为1.55%、1.29%和1.03%,偏心距为75mm。获得荷载-位移曲线并对应力云图进行分析,结果表明含钢率越小的组合墙体,它的平均最大压应力值和承载能力均会越小,而对组合墙的整体刚度影响很小,可见含钢率对轻钢-泡沫混凝土组合墙体偏心受压性能有很大影响,为同类试件偏压性能研究提供参考。In order to study the mechanical properties of the light steel-foamed concrete composite wall,ABAQUS finite element software was used to carry out the simulation analysis of the eccentricity compression of three specimens of the light steel-foamed concrete composite wall.The steel ratio of the three specimens was 1.55%,1.29%and 1.03%respectively,and the eccentricity was 75mm.Load-displacement curve was obtained and the stress nephogram was analyzed.The results showed that the smaller the combined wall steel ratio,the smaller its average maximum compressive stress value and load-bearing capacity will be,while little impact on the overall stiffness of the composite wall,visible steel ratio of light steel and foam concrete composite wall body had a great impact on the eccentric compression performance,which laying the foundation for the research of the same specimen bias performance.
