摘　　要：进行了4个不同形式的埋入式钢柱脚试件的试验,调查埋入深度和栓钉布置方式对埋入式钢柱脚受力性能的影响。通过实验,观察试件的破坏形式、分析比较了试件的荷载-位移曲线与弯矩-曲率曲线。同时建立了有限元分析模型,对埋入式钢柱脚进行多参数的数值模拟。实验研究和数值分析结果都表明,钢柱的埋入深度对钢柱脚的抗弯承载力与抗弯刚度有较大影响,合理布置栓钉能提高埋入式钢柱脚的抗弯承载力与抗弯刚度。Four samples of different embedded column bases were tested to investigate the influence of the different embedded depths and the arrangement of stud connectors on the loading behavior of the embedded column base. The experiment was used to observe the failure mode and analyze the load-deflection and moment-curvature of the samples. At the same time, a finite element analysis model was set up to numerically simulate the embedded column bases with many parameters. Both the experiment and the analysis show that the embedded depth of steel column greatly influences the bending capacity and stiffness of embedded column bases, so the proper arrangement of the stud connectors will increase the bending capacity and stiffness of the column bases.
