Abstract:Prestressed concrete(PC) channel bridge, consisting of a PC deck slab, two PC girders and two end crossbeams, is a new type of bridge structures. The PC channel bridges have been widely used in the structures such as highway, railway as well as urban rail transport. This paper presents a finite element method (FEM) analysis of mechanical behaviours of channel bridges with three girders in the construction, service and ultimate limit stage. The primary results include:(1) the channel bridges act elastically in … Show more
