【摘要】 以省内某高速上的一座双柱式连续梁桥为例,采用有限元分析软件Midas Civil建立空间三维模型,考虑桩土效应及材料的弹塑特性,依据现行公路桥梁抗震设计规范对其进行两阶段抗震分析,计算结果表明了结构设计的安全性,也为同类桥梁抗震设计提供参考和借鉴。更多还原

【Abstract】 For a highway double-column continuous beam bridge in Shanxi Province as an example, using the finite element analysis software Midas Civil, this paper established three-dimensional space model.Considering pile-soil effect and elastic-plastic proper ties of materials, according to the current highway bridge seismic design code, it carried out two stages of seismic analysis. The calculation results showed the safety of structure design and also provided the reference for the seismic design of similar bridges.更多还原
