摘要
本文利用Frame单元建立有限元分析模型,对主梁及导梁在顶推过程中的内力、变形以及各个支点反力进行分析,将计算结果与相应规范标准进行对比分析,为后续此类型桥梁施工过程中结构主梁及导梁力学性能计算提供参考。
Prefabricated steel box girder bridge has been widely used in bridge construction due to its advantages such as light weight,strong spanning ability,short construction period,long service life and low carbon emission.This article will use Frame element to establish finite element analysis model,the main girder and guide beam internal force and deformation in the process of pushing and various protection reaction were analyzed,and the calculated results with the corresponding standards,this paper compares and analyzes this type of bridge construction process for subsequent structure girder and provide reference for the structural behavior calculate.
