摘要
依托某跨径为3-20m预应力混凝土连续空心板桥,采用Midas/Civil 2012建立了该桥不同桥墩墩柱高度的三维有限元模型,验算在E1、E2地震作用下,该桥墩墩柱强度及延性。
Based on a prestressed concrete continuous hollow slab bridge with a span between 3 to 20 meters, a three - dimensional finite element model of the bridge＇s different pier columns＂ hights by using program Midas/ Civil 2012 is established, check and caculate the strength and ductility of the pier columns under E1 and E2 seismic actions.
