摘要 进行了高温作用后型钢混凝土柱力学性能试验,在试验的基础上建立了高温作用后型钢混凝土柱力学性能的数值模拟方法。通过在ABAQUS平台上开发子程序建立了升降温作用下型钢混凝土柱温度场的计算模型,通过选择合适的材料本构关系以及在ABAQUS平台上开发自定义场变量子程序,在考虑升温、降温以及高温作用后不同阶段材料本构关系的基础上,提出了高温作用后型钢混凝土柱力学性能分析的计算模型,实现了高温作用后型钢混凝土柱力学性能的计算模拟。计算结果与试验结果的对比表明,二者吻合较好,提出的方法合理可行。 An experiment was carried out to study the post fire performance of steel reinforced concrete (SRC) columns, and a numerical simulation method for the post fire performance of the SRC columns was proposed on the basis of the experimental study. A finite element model for the temperature analysis of the SRC columns exposed to fire including the heating and cooling phases was proposed by programming a subroutine based on the ABAQUS software. At the same time, a numerical simulation method for the post fire performance of the SRC columns subjected fire including the heating and cooling phases was proposed, and the material constitutive relations in the heating phase, cooling phase and post fire phase were considered in this method. The numerical simulation was carried out by choosing the appropriate material constitutive relations and developing a user field subroutine on the platform of the ABAQUS. It shows that the calculation results agree well with those of the test results, which shows that the proposed numerical simulation method is reasonable.
