摘要
基于非线性有限元ABAQUS,建立了考虑温度和荷载耦合作用下的型钢混凝土柱耐火性能的理论计算模型,将理论计算结果和试验结果进行对比,对比结果表明理论计算和试验吻合较好,验证了本文提出有限元模型的有效性。
Based on nonlinear finite element software of ABAQUS, theoretical calculation of steel reinforced concrete column model under the coupling effects between temperature and load is established, and the theoretical calculation results are compared with experimental results. The comparison results show that the theoretical calculation and experiment are in good agreement. The finite element model is proven to be effective which is proposed in this paper.
