Abstract: The shear‐lag effect in a thin‐walled box girder has been recognized and introduced in the technical literature. In contrast however, a discussion of shear‐lag effect caused by the combination of prestress force and ...

Abstract: In this paper, derivation and computed formulas are provided for the shear lag coefficient in a simply supported prestressed concrete box girder under dead load. In the case of prestressed tendons having parabolic ...

Abstract: A finite difference solution is presented for shear lag effect on the box girder with varying depth. The analysis is carried out according to Reissner's method in which the spanwise displacement is assumed to be a quartic ...

Abstract: A spline finite strip approach is presented to analyze the cantilever deck of single‐cell box girder bridges. The effects of distortion of a thin‐walled box section are taken into account by treating the cantilever deck ...

Abstract: Shear lag and negative shear lag effect in cantilever box girders are analyzed through a variation approach and finite element techniques. The complex distribution of bending stresses under symmetrical loading on the flanges ...
