A rebar coupler is used to connect two adjacent rebars in new construction and in retrofitting works. This can be used to connect the new rebar with extended rebars in the existing concrete elements. However, in several cases the performance of conventional rebar couplers was not found satisfactory during the earthquake. To improve the performance of spliced region, hybrid rebar coupler has been developed and upgraded. This coupler consists of a cylindrical steel sleeve with internal threads to offer frictional resistance between the rebar and sleeve. The cylindrical sleeve has provisions for vertical and inclined bolts to apply lateral pressure. It can be used to connect precast structural elements at the potential hinge region of framed structures.
