FLEXURAL BEHAVIOR OF HYBRID FRP-CONCRETE BRIDGE DECKS

The main aim of this study is to investigate the behaviourof hybrid FRP-concrete decks. The hybrid FRP-concrete bridge systems consisting of different FRP cell units available on the market such as trapezoidal, triangular, honeycomb, rectangular with alternating diagonal, half-depth trapezoidal, hexagonal and arch cell units were computationally compared and examined using the finite element (FE) analysis to decide the most appropriate FRP composite deck for bridge systems. Design criteria such as the deflections were considered in selecting the most effective unit system. Different FRP bridge deck panels were analysed under static loading representing the standard European truck wheel. The finite element analysis of bridge deck systems was performed using a general purpose finite element analysis package ABAQUS, and the behaviour of these systems was then be compared in terms of stiffness and strength criteria. The results showed that Delta, Super and ASSET hybrid decks are stiffer than other deck systems. The results from FEA approach also indicated that the layer of concrete on the top surface of bridge deck reduces the vertical displacement of FRP bridge systems approximately 60%
