ABSTRACT The paper presents a beam model for the analysis of composite decks taking into account the warping of the slab cross section and the partial shear interaction between the slab and the girders. Slab shear-lag is taken into account by means of the product of a known function, describing the shape of the slab crosssection warping, and an intensity function measuring the magnitude of warping along the beam axis. The numerical solution is obtained by means of the finite element method with a new 13-dof beam element. The results of a number of applications of the proposed model to a realistic bridge deck are compared with those obtained by means of shell finite elements, showing the accuracy of the proposed element.
