摘要
通过对低配筋大比例尺铁路桥墩模型的伪静力试验,对试件的破坏形式进行分析,研究了低配筋铁路桥墩的延性抗震性能,分析其位移延性比、转角 位移曲线的包线与剪跨比、配筋率、配箍率之间的关系,得出了桥墩抗震设计的基本参数。
The paper studies the hysteretic inelastic characters of 10 large-scale RC railway pier models with low steel ratios. Destructive reasons of the models are analyzed. The ductility ratio, maximum force-resistance and embracing curve are calculated. The relationship of the shear span ratio and confinement ratio with the ductility ratio, maximum force-resistance and embracing curve are analyzed. Basic parameters for aseismic design of RC bridge piers with low steel ratios are obtained.
