Perfobond Shear Connector for Composite Construction

Abstract

Composite construction produces stiffer, stronger sections by the efficient use of both steel and concrete. The desirable composite action, however, is not possible unless adequate shear transfer at the steel member-concrete interface is provided. During the last several decades, several types of shear connectors have been developed to insure this transfer of shear; the most common connector is currently the headed stud. This type of shear connector requires a certain amount of slip to occur before composite action can be established. A new type of shear connector for composite construction, called the Perfobond shear connector has recently been developed to eliminate some of the problems and difficulties associated with standard shear studs. A coordinated experimental and analytical study was undertaken to further examine the behavior of composite members utilizing the Perfobond shear connectors, and to develop a reasonably simple, yet reliable design equation.
