Abstract
The chapter presents a beam model for the analysis of composite decks, considering the warping of a slab cross-section and the partial shear interaction between the slab and girders. Slab shear-lag is considered by means of the product of a known function, describing the shape of the slab cross-section 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.
