This paper focuses on the current state of the steel truss bridges in construction and development of alternative bridge such as FRP Bridge. A model of FRP truss bridge is fabricated at structural testing centre of BITS Pilani. In order to overcome the deficiencies of steel bridges, a FRP truss bridge is proposed. The experimental response of the FRP truss bridge is predicted under static loading. Further, truss bridge is modelled using ABAQUS and it is observed that experimental and numerical responses are in good agreement with each other. From the numerical study, it is noted that without stiffening of the top chord, truss deflect in the lateral direction as well as top chord buckles before overall failure of the bridge. From this study, it is concluded that connection of the top chord with horizontal strut is more efficient than vertical strut. Top chords and struts of FRP truss bridges made by CFRP and the floor beams made by GFRP box section are economical and efficient for heavy loading |
