摘　　要：使用ABAQUS对新型C型钢–轻质混凝土组合板模型进行分析,其主要包括两种材料的本构关系、材料屈服准则的模型构建以及有限元模型单元的选取等内容。通过模拟得到组合板的位移应力云图与荷载–挠度曲线、C型钢的荷载–应变曲线以及组合板的最大塑性应变矢量图与最大塑性应变云图破坏形态。结果表明,组合板处于弹性阶段时的应变增长较缓慢,随着荷载增加,应变值呈现出线性增长,处于弹塑性与破坏阶段时,应变值呈现出非线性增长,且应变增长速度有明显的提高。This paper uses ABAQUS to analyze the new C-type steel and light-weight concrete composite plate model, including create constitutive relation and material yielding rule models of these two materials, as well as selection of finite element model unit. Simulation was carried out to get displacement stress nephogram and load-deflection curve, C-type steel load-strain curve, maximum plastic strain vectorgraph and maximum plastic strain nephogram failure state. It was found that strain of the composite plate increases slow during the plastic phase and the strain value increases after the increase of load. During elastic-plasticity and failure phases, the strain value has nonlinear increase and the strain increase speed becomes obvious faster.
