Shear strength of T-type Perfobond rib shear connectors

In this research, a T-type Perfobond rib shear connector for steel concrete composite bridges is suggested, and a series of push-out tests are performed with numerous parameters, such as length and thickness of the ribs, diameter and number of the holes in the ribs, number of transversal reinforcing steel bars, and strength of concrete. Based on the test results, the effect of each parameter is analysed. Also, a shear strength evaluation formula is suggested for a 400 mm long T-type Perfobond rib shear connector. Comparison of the test results and the calculation results, using the suggested formula, validates that the suggested formula rationally evaluates the effect of considering parameters.
