摘　　要：通过低周反复加载作用下5根翼缘加焊栓钉的HSRC框架柱的拟静力试验,研究了HSRC框架柱在压弯剪共同作用下的破坏特征和抗震性能;由试验获得的滞回曲线,得到了各构件的骨架曲线、延性比等;分析了不同布置形式和不同数量的栓钉对HSRC框架柱抗震性能的影响。结果表明:翼缘加焊栓钉的HSRC框架柱的延性显著提高,抗震性能明显增强;栓钉的布置形式对HSRC框架柱的抗震性能有较大影响,错位排列且布置在离柱脚300mm范围内的栓钉布置形式是合理的。For researching the seismic behavior and failure characteristic of HSRC columns under compression, bending and shearing, a pseudo-static test containing 5 specimens is conducted under cyclic loading. By the analysis of hysteresis curves, skeleton curves and ductility ratios of members are obtained. In the interest of the effect factors of welded studs on flanges, these studs are arranged in different locations and numbers. The results demonstrate that the welded studs on flanges made considerable improvement on the ductility and seismic behavior of HSRC columns. It was verified that the best arrangement of studs is stagger arrangement in the 300mm area of heel post.
