为了研究HRBF400钢筋配筋（hrbf -高强度细晶粒热轧钢筋）钢筋混凝土柱的抗震性能，对4根矩形截面HRBF400钢筋混凝土柱进行了低周反加载弯曲试验。分析了配筋率、轴压比和配箍比对HRBF400钢筋混凝土柱抗震性能的影响。研究了试件的滞回曲线和骨架曲线特征，计算了各试件的特征值和位移延性。结果表明，HRBF400混凝土柱具有良好的抗震性能。屈服荷载、峰值荷载和延性随配筋率的增加而提高。高压缩比柱的峰值荷载和屈服荷载较高，但峰值荷载后骨架曲线下降快，延性较低。低压缩比柱的峰值荷载和屈服荷载较低，峰值荷载后下降平缓，延性也较好。钢筋混凝土柱的抗震性能和延性随着配箍比的增大而改善。
In order to investigate the seismic behaviors of RC columns reinforced with HRBF400 steel bar (HRBF-high strength hot rolled bars of fine grains), four rectangle cross-section HRBF400 RC columns' bending low-cycle reversed loading experiments were made. Influences of reinforcement ratio, axial compression ratio, and stirrup ratio on the seismic behaviors of HRBF400 RC columns were analyzed. Characteristic of hysteretic curve and skeleton curve are studied, and characteristic value and displacement ductility of each specimen was calculated. The results show HRBF400 RC columns have good seismic behavior. Yield load, peak load, and ductility improve with the increasing of reinforcement ratio. Columns of high compression ratio have high peak load and yield load, but their skeleton curves decrease quickly after peak load and have low ductility. Columns of low compression ratio have low peak load and yield load, but decrease gentlly after peak load and also have good ductility. Seismic behaviors and ductility of RC columns improve with the increasing of stirrup ratio.
