The main aim of this study is the design of superstructure of a RC T-beam bridge by varying spans. Tbeam bridge decks are one of the most important types of cast-in-situ concrete decks. T-beam Bridge comprises of a concrete slab integral with girders. The finite element method is a common technique for the analysis of complicated structure. In Finite element method the structure or continuum is discretized into finite element and they are interconnected with each other through nodal points and symbolize the answer for the problem. To compute the bending moment due to Live load in a girder and Slab Bridge, the distribution of the live loads among the longitudinal girders has to be determined. A simple span Tbeam bridge was analyzed by using I.R.C. loadings as a one dimensional structure. The same T-beam Bridge is analysed as a three-dimensional structure using finite element software SAP 2000, v14.2.2. Both models are subjected to I.R.C. Loadings to produce maximum bending moment. The results obtained from the finite element model are lesser than the results obtained from Courbon's method, which means that the results obtained are conservative.
