摘要 对9个方钢管混凝土柱试件进行了低周反复试验,截面尺寸为500 mm×500 mm,钢管壁厚10 mm。依据钢管内壁焊置栓钉数量的不同将试件分为无栓钉、单排栓钉(栓钉间距250 mm)、双排栓钉(栓钉间距167 mm)三组,每组三个试件,分别采用0.4,0.5,0.6和0.8的试验轴压比。试验表明,高轴压比试件滞回曲线狭小,延性差,低轴压比试件滞回曲线饱满,延性较好;随着栓钉布置的增多,试件的水平峰值荷载略微增大,荷载位移延性略微降低。 Nine specimens were designed,of which the cross section was 500 mm×500 mm,and the steel tube was 10 mm thick.The specimens were divided into 3 groups according to different stud arrangements,with each group containing 3 individuals.The specimens were tested under different axial compression force ratio including 0.4,0.5,0.6 and 0.8.The experimental results indicated that the axial load level has a significant influence on the strength and ductility of the concrete filled rectangular steel tubular(CFRT) columns,high axial load level will lead to poor seismic performance and low axial load level will improve the ductility of the specimens.It was also showed that with more stud welded in the steel tube,the peak strength increases a little,and the ductility declines slightly.
