Özet
In timber concrete composite systems, the shear connector which ensures the connection between the concrete slab and the timber beam is a critical component influencing the overall behavior of the system. In previous studies, all designed shear connectors were fully embedded in concrete. Consequently, the damage occurred not only in the shear connector but also in the concrete slab and timber beam. In this study, a new perspective on shear connector design has been introduced. In the proposed design, the shear connector is partially isolated from the concrete, providing a space that allows it to bend freely within the slab. This configuration delays damage in the concrete slab and timber beam, leading to damage localization on the shear connector itself. Even at advanced damage levels, the structural integrity of the system can be maintained. As part of the experimental program, pushout tests were conducted on nine full-scale asymmetric specimens, and bending tests were performed on three beams with a length of 450 cm. The load-carrying capacities, stiffness, energy dissipation capacities, and damage patterns of the specimens were determined and compared with those of conventional shear connectors.
