This study covers bonding behavior of bolted timber-concrete composite beam. Timber-concrete composite (TCC) system is a construction technique that gives benefit in upgrading both strength and stiffness of existing timber structures. This system can be attractive for both refurbishment and new build projects. The process involved by attaching connectors to the surface of the timber plank and placement of concrete on top of it. In addition, the use of formwork can be minimized as the timber plank can be part of the formwork. Six samples of timberconcrete composite beam with different configuration of bolt connector are presented and all samples were tested under four point bending test including one additional sample as controlled sample. It is shown herein, different ultimate resistance of TCC beam is obtained for different configuration of bolt connector. Based on the results, inclined bolt leads to high slip stiffness. TCC system shown good effect on the performances in terms of ductility since almost all samples could sustain the applied load for slightly long time than solid timber beam alone. However, it is observed that interface slip was occurred at all specimens.
