摘要

运用有限元程序Midas/civil对钢管混凝土叠合柱桥墩在E1、E2地震作用下的抗震性能进行弹塑性分析,并与因阻水超限而不便采用的钢筋混凝土桥墩的计算结果进行比较.结果表明钢管混凝土叠合柱桥墩的承载、延性性能均优于钢筋混凝土桥墩.该结论能为同类桥梁在偶遇荷载作用下的设计提供参考,同时为在桥梁下部结构中采用钢管混凝土叠合柱的新的设计理念提供有利支持.
Elastic-plasticity analysis about composite column with concrete-filled steel tube bearing earthquake action E1 and E2 is carried out.The results are compared with the ordinary reinforced concrete column which isn't adapted to use because of super limit baffling water according to the objective need about the project.The ultimate bearing capacity and ductility function are superior to theirs of reinforced concrete pier.The conclusion can be referenced for the design of similar bridge under the accidentally load.In the meantime,the conclusion can provide the beneficial support that the new design thought of composite column with concrete-filled steel tube used in the bridge's substructure.
