Reinforced Concrete (RC) structures deteriorate due to several reasons including corrosion of steel. Once the bond between the concrete and steel is lost, the reinforcement becomes ineffective. There are several cases of failure of bridges due to this limitation of reinforced concrete. Glass Fiber Reinforced Polymer (GFRP) bridge deck panel is an alternative for conventional RC panel in bridges which remains unaffected by environmental attack. The paper discusses the results of the analytical study on the fatigue behavior of GFRP bridge deck panels. Finite element software ANSYS is used for modeling and analysing multi-cellular GFRP bridge deck panels. The analysis shows good performance of GFRP panels under fatigue load.
