摘　　要：对国家体育场柱脚进行抗拔性能试验研究与分析,详细描述了试件设计制作与破坏过程,给出了试件的荷载-位移骨架曲线.在此基础上,分析研究了混凝土承台开裂、破坏的全过程,同时,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荷载-位移情况进行了数值分析,并与试验结果进行了对比,计算结果与实测结果符合较好.This paper presents an experimental and theoretical study on anti-pulling properties of column base of National Stadium. The design of specimens and the failure procedures are described in detail. Besides, the ＂load-deflection＂ skeleton curves are given. Based on the results, the evolution of crack patterns and failure mode of pile caps are investigated and compared. Nonlinear finite element analysis of pile caps of steel column base under unilateral load is also carried out by ANSYS program. Agreement is obtained between theoretical and experimental results.
