Shear Strength of Perfobond Rib Shear Connector according to Concrete Strength and Rib Arrangement

摘要

This paper deals with the perfobond rib shear connector which takes a role of bonding two different materials for composite structure. For the purpose of this research, push-out tests are conducted to exam the shear strength of perfobond rib shear according to concrete strength and rib arrangement. Therefore,push-out specimens, which were in two rows rib with different intervals and its concrete strengths are varied, were fabricated. As a result of this re search, the shear strength was evaluated. The shear strength of perfobond rib shear connector is in proportion to the concrete strength. The shear strength of perfobond rib shear connectors with two rows is evaluated to be about 80% of single's.
