Multiscale Analysis of Arch Hollow Continuous Beam Bridge Structure
Arch shaped hollow continuous beam bridge,as a new type of bridge formed by combining arch bridge and continuous beam bridge,integrates the characteristics of beam bridge and arch bridge.It has a beautiful structural shape,and good adaptability to surrounding landscapes and sites.It has a large application space in modern urban landscape bridges.The V-shaped section structure of the main pier of an arched continuous beam bridge is complex,especially the structural form and stress characteristics of the beam arch combined with the triangular crossbeam.It is difficult to accurately calculate the stress distribution based on the overall analysis of the beam system finite element structure,and more detailed solid finite element analysis is often required.This article first conducts an overall analysis of the bridge structure using the rod finite element method,and then conducts a local analysis of the beam arch combined with the triangular beam using the solid finite element method.By using a multi-scale analysis method that combines the whole and the local,a detailed calculation of the arch hollow continuous beam bridge structure is carried out,providing a basis for the design optimization of the arch continuous beam bridge,and has certain reference significance for the design of this type of bridge structure.
