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。
The quasi-static tests of HSRC frame columns with five flanges and welded studs under low cyclic loading were carried out to investigate the failure characteristics and seismic performance of HSRC frame columns under the combined action of compression and shear. The hysteresis Curve, the skeleton curve and ductility ratio of each component were obtained. The influence of different arrangement forms and different numbers of pegs on the seismic performance of HSRC frame columns was analyzed. The results show that the ductility of the HSRC frame with flange-welded studs is significantly improved and the seismic performance is obviously enhanced. The arrangement of the studs has a great influence on the seismic performance of the HSRC frame columns, which are arranged in a staggered manner and arranged at a distance of 300mm Inside the stud layout is reasonable.
