Structural Performance of Retrofitted Bridge Deck Slabs Using CFRP Strips under Cyclic Loading

Abstract eng:
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%.
