T-beam bridge deck is a structural element composed of deck slab rigidly integrated with main longitudinal girders. In structural analysis, the finite element method is a numerical procedure for modeling of complex geometry and irregular shapes as easier as varieties of finite elements are interconnected at different nodes provides the solution domain of problem. In this study, a simple span T-beam bridge was analyzed using courbon’s method by considering IRC loadings. Further the same bridge model is analyzed using finite element method for both deck slab and T beam integral with girders using STAAD V8i SS6 software for four different spans of 25m, 30m, 35m and 40 m. All analysis is carried out with suitable IRC Vehicular Loadings. Both FEM and Courbon’s analysis are subjected to IRC class AA and IRC 70R tracked vehicular loading system in order to obtain maximum bending moment and shear force. From analysis it is observed that the results obtained from courbon’s method are greater than the results obtained from finite element analysis, this shows that the rational computations are conservative and staad values impart reasonable design. The value of shear force in rational method is less than that of finite element analysis due to load combinations and maximum SF occurs in IRC class AA Tracked vehicle.
