합성작용을 위한 새로운 Perfobond T형 전단연결재

A New T Type Perfobond Shear Connector for Composite Action

The results and interpretations of push-out tests on shear connector devices for composite bridges carried out in this study are presented. The devices under investigations are headed studes, perfobond rib, ㄱtype perfobond rib, T- Connector and a new type of shear connector called T type perfobond rib. This new connector is flat steel plate with a number of holes punched through. The results obtained indicate that the T type perfobond rib shear connectors exhibit adequate ductility and substantially higher capacities. Therefore for composite beams utilizing reinforced concrete slabs, the T type perfobond rib shear connectors is a viable alternative to the headed studs.
