摘　　要：为了确定露出型低位锚栓钢柱脚的抗剪承载力,对该类型柱脚分两种构造形式进行试验研究,一种用于研究锚栓的抗剪性能,另一种用于研究抗剪键的抗剪性能。通过试验研究和理论分析,得出柱脚抗剪P-δ滞回曲线,提出露出型低位锚栓钢柱脚在不同构造时整体抗剪承载力计算公式,并对GB 50017-2003《钢结构设计规范》中关于钢柱脚设置抗剪键方面的规定提出修改建议。In order to determine the shear capacity of low anchor bolt in steel column base. Two constructions of steel column base were studied by experiment. One is on the shear behavior of anchor bolt, and another is on shear behavior of shear connector. According to experimental study and theroretical research. P- ~ hysteresis curues were obtained. The formula of shear capacity for exposed-type column base in the low anchor with different constructions is put forward. And some revision are provided about setting sheer key on the column base of Code for design of steel structures （GB 50017--2003）.
