| 摘 要： | 针对铁路桥梁中使用量最大、应用最广泛的单柱式桥墩,通过24根大比例的桥墩模型的伪静力试验,研究了其延性抗震性能.通过对试验现象及数据的分析,研究了这类桥墩的力—位移关系、滞回模式的变化规律;比较分析了配筋率、配箍率、箍筋布置形式、剪跨比等结构参量对试验模型的耗能特性和包络曲线特性的影响.归纳总结了试验中典型的破坏现象,并对产生这些破坏现象的原因进行了分析.在以上分析基础上,得出了改进单柱式桥墩抗震性能的有关结论和建议,可供我国铁路桥梁延性抗震设计参考. |

| Abstract: | The ductile earthquake performance of one-column bridge piers,which are used frequently at the railway bridge,is studied by pseudo-static test for 24 large-scale pier models.According to the test data,the force-displacement relation and hysteresis hoop are studied.Furthermore,consumption energy characteristics and envelope curves of the models are analysed,and the influence of the test parameters,such as longitudinal reinforcement ratio,hoop reinforcement ratio and shear-span ratio,are compared.After that,the causes for the failure phenomenon of the models are explored.Finally,Related conclusions and advice are provided for the ductility anti-earthquake design of railway bridges in China. |
| Keywords: | bridge pier ductility anti-earthquake pseudo-static test |
