Bearing Capacity of Perfobond Rib Shear Connectors in Composite Girder Bridges

AbstractPerfobond rib shear connectors are used widely in bridge engineering, and expressions for their shear capacity can be found in various codes and standards. Empirical expressions available for the strength of perfobond rib shear connectors have been obtained mostly by the numerical regression analysis of push-out test results. Because of discrepancies in both specimen dimensions and the test procedures, the various test results do not agree with each other, and the empirical strength predictions so derived are quite different. To resolve this discrepancy, the authors investigated the modes of failure of perfobond shear connections using a novel push-out test procedure. The mechanisms for the resistance to load of perfobond rib shear connectors were analyzed, and the effects of the concrete and transverse reinforcement on the shear resistance were investigated. An empirical expression for the shear strength of perfobond rib shear connectors with transverse reinforcement is proposed here. The calcula...
