In reinforced concrete structure, rebar connection method should be considered because of its structural role to resist the tensile stress and its structural load transmission with concrete in the concrete structure. Lapped splice and mechanical sleeve type connector have been traditionally used to connect rebar in the concrete structures. In this study, to examine the mechanical and failure behaviors of rebar bar connected by taper type coupler in the concrete member depending on connection type and condition, tensile tests of steel rebar with taper type coupler and flexible loading tests of concrete beams were conducted. Its tensile strength and flexible strength of the rebar connected by taper type coupler were compared and evaluated by mechanical behaviors of rebar. From this study, steel rebar connected by taper type coupler showed it has similar mechanical performance comparing with unconnected rebar, thus taper type coupler can be used in the rebar fabrication of reinforced concrete structure.
