“321”型上下承式贝雷梁受力性能对比分析

Comparative analysis of stress performance of “321” type bailey beam with deck type and bearing type

以上承式和下承式两座结构形式不同的"321"型贝雷梁为研究背景,基于Midas/Civil有限元分析软件,对两种结构的静力性能进行了计算,并结合现场荷载试验数据结果对其进行了对比分析,总结出了一些规律,旨在为今后同类型桥梁的设计和检测提供一定的参考作用。

This deck type and bearing type two different structure form＂321＂type bailey beam as the research background,based on finite element analysis software Midas/Civil,the static performance of the two kinds of structures are calculated,and combining with the results of load test data for analysis,and summed up the rules and provide reference for the design and test of the same type bridges in the future.
