-The effect of various span on single-span reinforced concrete bridges and PSC bridges are analysed using the finite-element method and the results are presented in this paper. Investigations are carried out on RC slab bridge decks and PSC bridge decks to study the influence of aspect ratio, span and type of load. The finite-element analysis results for bridges are compared to the reference analytical solution for dead load, IRC Class AA loading. Also comparative analysis of response of RCC and PSC slab bridge decks with that of equivalent of FEM analysis of bridge deck is made. Number of bridge models is analysed and the variation of critical structural response parameters such as longitudinal bending moment, longitudinal stresses and support reaction with analytical solution is studied. The benefit of prestressing is reflected more significantly increase in longitudinal bending moment and longitudinal stresses.
