STRUCTURAL PERFORMANCE OF RETROFITTING BRIDGE DECKS LABS USING CFRP STRIPS UNDER CYCLIC LOADING
FRP composites have been widely used as internal and external reinforcement for concrete bridge deck slabs. However, experimental and numerical researches on the behavior of such FRP-reinforced elements in general have been limited, especially those on cyclic performance. This study evaluates the force-deformation responses of retrofitted bridge deck panels under cycling loading up to the failure. The numerical analysis is carried out in ANSYS environment. Punching shear is a common mode of failure of restraint concrete bridge deck specimens reinforced with steel or FRP composite bars under cyclic loading. Ruminating results indicates the greatest capacity achieved by FRP lay-up (0, 90). Using CFRP strip systems result in considerable upgrading of the structural capacity of deck slabs up to 24%.
