The Arched Bridge Arches Constructs Participates In The Host Arch Ringjoint Action Research

With the rapid development of China's socialist cause, the cause of traffic demands large-scale development. In this article, we explore knowledge of arched bridge. Among the arched bridges in the active service, there are some problems. The article mainly studied the following aspects:1) for the arched bridge whose arch springs are split, it not only produces thrust, it should also be a bending moment. So flat hinged arch theory is more suitable;2) for the arched bridge in the joint role of the construction on the arch, they can be simplified into a spring-loaded model which replaces solid-belly style or open web upper structure, namely, the use of spring-loaded to replace the bridge arch. This assumptions can simplify mechanics models, is convenient for analysis and the results of the analysis are accurate;3) apply Adina to the spring model and the actual bridge model for the finite element simulation analysis, make a comparative analysis of the two models, reach a conclusions that the two structures are similar.
