Abstract: Most studies on shear lag effect in box girders are only concerned about concentrated loads and uniformly distributed loads. In this paper, a finite-element method based on the variational principle is presented to analyze ...

Abstract: A finite-element method considering the interaction of the bending and shear-lag deformation of a box girder was established. Meanwhile a shear-lag-induced stiffness matrix was defined. The stiffness matrices considering ...

Abstract: In this paper, a conception of load-induced stiffness matrix is developed, and a beam element for using the finite-element method, which takes into consideration the stiffening effect of dead loads, is proposed. The element ...
