摘　　要：通过装配式混凝土框架钩挂式中柱节点的前期试验数据,利用ANSYS软件构建模型并进行有限元分析。通过对多种参数进行调试和低周往复荷载模拟,得出与实际试验相似的结果。结果表明,摩擦系数、裂缝系数、本构关系、约束、边界条件和接触对等参数是试验重点调节的数据,通过不断调试这些参数,得出与试验相一致的试验结果。通过非线性数值模拟得到相近的最不利点,研究最不利点对实际构件有一定的指导作用,由此变换构件样式或参数,降低最不利点的不利影响。Based on the preliminary test data of hook-and-hang typed midcolumn joints for prefabricatedconcrete frame,the model is built and the finite element analysis is carried out by using ANSYS software.By debugging various parameters and simulating low cycle reciprocating load,the results are similar to theactual test.The results show that the friction coefficient,crack coefficient,constitutive relation,constraint,boundary condition and contact equivalent parameters are the key adjustment data for the test.By continuouslyadjusting these parameters,the test results consistent with the test are obtained.The most unfavorable pointsare obtained by nonlinear numerical simulation.The research on the most unfavorable points has a certainguiding role for the actual components,so as to change the component styles or parameters,and reduce theadverse effects of the most unfavorable points.
