摘要
通过对大瑞线漾濞1#桥8#桥墩的弹塑性抗震分析,研究圆端型铁路空心高墩的地震反应作用机理,用纤维梁柱单元模拟桥墩,分析塑性铰发生部位,为铁路桥梁空心高墩的抗震设计提供一些有用的数据和理论依据.
Based on the elastic-plastic seismic analysis of the eighth pier of 1st Yangbi bridge of Darui major railway,the earthquake responsive mechanism of hollow round nose of high pier of railway is studied by simulating pier with fiber beam-colomun element and analyzing plastic hinge location,which provides some useful data and theoretical basis for the railway bridge seismic design of hollow high pier.
