摘　　要：文章通过对3组(共12件)配箍率不同的钢筋混凝土桥墩缩比模型分别在拟静力作用和弹塑性静力推覆作用下的试验,深入研究了钢筋混凝土桥墩的破坏型态、滞回曲线、骨架曲线、残余变型率、耗能能力和刚度退化等抗震性能;试验结果表明,随着配箍率的增大,构件的各方面抗震性能均有所提高。The experiments are conducted on three groups of scaled model of reinforced concrete bridge pier, both the pseudostatic test and the static pushover test are carried out ,and the failure pattern, hysteresis curve, skeleton curves, remnant distortion ratio, energy dissipation, and rigidity degeneration of the pier are studied systematically. The study results show that with the increasing of the stirrup reinforcement ratio the member＇s seismic performance is improved.
