Title: Analysis on Local Stress of Linked Part of Steel-Prestressed Concrete Composite Continuous Beam Bridge
Abstract: As a new type of structure,steel-prestressed concrete composite continuous beam brigde makes junction of steel box and concrete box beam as its most critical structure,in order to transfer the various loads smoothly.This paper takes a bridge as the background,based on the complex characteristics force of mixing department of long bridge,using the finite element analysis method,established the finite element model of combination of the bridge′s steel-concrete,calculated under the condition of the relevant load cases.The results show that there is a small number of steel concrete composite section stress exceeding the allowable value,and high stress concentration in the tiny area and the whole structure is in a smaller state of stress,the entire section of the bridge and steel concrete composite performance are safety of overall.
