Characteristics of Force Transmission of the Junction for Steel-prestressed Concrete Composite Continuous Beam Bridges

摘要

A steel-prestressed concrete composite continuous beam bridge is one of new type navigational bridge structures with economic and clear mechanic behaviors. The junction of steel and concrete beam is the critical part, which makes the two different materials to be continuous structural system and transfer different kinds of loads reasonably. This article takes the Chang Bridge which locates on G318 state road in Changxing County, Zhejiang Province as the background to analyze the characteristics of transferring bending moment in the junction by the finite element method. The results show that the junction of steel and concrete designed can transfer loads smoothly. Therefore, the junction can be further researched for extensive application.
