| 摘 要： | 在试验研究基础上，采用ANSYS有限元分析程序，对钢柱脚混凝土承台在单向加载下的性能作了弹塑性分析，研究了其在竖向抗拔荷载作用下的开裂、变形及破坏的全过程，并在此基础上，建立了简化的抗拔承载力计算的桁架模型，计算结果与试验结果符合较好。

| Abstract: | In this paper, nonlinear finite element analysis of pile caps of steel column base under unilateral load is carried out by ANSYS program. The evolution of crack patterns, deformation and failure mode of the pile cap under uertical pull resistant loading are studied based on the experiment, and the simplified mechanic model is proposed. The calculated results agree well with the results of the experiment. |
