Joints stress analysis of a prestressed-concrete slant-legged rigid frame bridge

In this paper,shell element of the finite element program is used to analyze the joints stress of a long span prestressed concrete box girder rigid frame bridge with raking legs.Furthermore the shear lag of box girder is studied with the finite shell element method.The analysis method more rationally and realistically calculates the stress of all bridge,which is of practical significance for design and construction of this kind bridge.
