A Study on Shear Strength of the Perfobond Rib Shear Connector for Composite Beam

Abstract:

For safe and efficient use of the Perfobond Rib shear connector, it is essential to investigate mechanical behaviors and evaluate performance of shear resistance. When the Perforbond Rib shear connectors are to be used for a structure, they show flexural-shear behavior due to external force rather than direct shear behavior. Therefore, this study performed a direct shear test and proposed the equation for the shear resistance assessment. Also, a flexural shear test was conducted. Through the direct shear test, main factors that affect directly shear resistance were found. The flexural shear stress and the direct shear stress were calculated and it is revealed that the flexural shear stress is approximately 6% stronger than the direct shear stress.
