T-beam slab deck bridge is the most common type of superstructure generally adopted in most of the highways in the country. Moving live load combinations are the critical loadings for which bridge deck needs to be analyzed. In this paper, T-beam slab bridge deck is modeled using finite element method by assuming it as a beam–plate model. In beam–plate model, the beam element is assembled in the plane of the plate element, so that the center of gravity of the beam coincides with the plate element. Live load for Class 70R wheeled vehicle, on a two-lane bridge is taken as per IRC: 6-2016. The analysis is performed as per IRC: 112-2011. The study on the three different cases of cross girder combinations is considered. The effect of number of cross girders is analyzed in order to reduce the maximum bending moment and deflection in longitudinal girders on the bridge deck model. A MATLAB code is developed for finite element modeling of T-beam slab deck bridge. The results of various combinations of loads for the maximum value of shear force, bending moment, and deflections are tabulated and plotted.
