Finite Element Simulation Analysis of Force Conditions of Large Span Continuous Box Girder Bridge with Cantilever Construction

Juan Hu

Abstract

By means of Midas/Civil2006 software,the whole bridge can be simplified into three-dimensional model,the simulation analysis of the whole process of bridge froce conditions from construction state to completion state can be performed.The large span continuous box girder with the span of 70m+1250+70m which crosses the existing railroad was analyzed.The results of calculation show that the method can well fulfill precise simulation of the whole process of the actual force conditions of the structure of the bridge,therefore contributing an effective means of verifying construction and supplying technical data for the similar large span continuous box girder.
