Abstract
Recently, many types of the composite shallow beam have been developed in order to minimize the depth of floor-beam structures and to save the cost of headed-shear studs. In this new type of composite structure, the shallow-hollow composite beam consists of web openings, filled with in-situ concrete (concrete dowel). This article presents an experimental study to investigate shear strength and shear transferring mechanism of the concrete dowel with trapezoid shape. A series of static push-out tests have been conducted. The tested results provide information on the behavior and shear performance of the specimen. Shear transferring of concrete-filled web opening connectors reveals that the concrete dowel behavior could be divided into crushing, compression, and tension zones.
