Review on Shear Connectors in Timber-Concrete Composite Beams

The timber-concrete composite (TCC) beam is a new type of structural member, which formed by combing a timber beam and an upper concrete flange using different types of connectors. Compared with the traditional timber beam, the bending and stiffness of the composite beam is proved. In composite structure, the important factor of the structure is the shear connector. So structural efficiency of a TCC highly depends on the stiffness of the interlayer connection. This paper presents a survey on the state-of-the-art of shear connectors for TCC beam research in the past and recent years. And put forward to the subsequent study of shear connectors in TCC beams.
