This study was performed to develop a reinforcing head method for steel pipe piles using screw type bending reinforcement, which can fix piles using nuts, and experimentally prove structural performances. In order to do so, steel pipe pile reinforcing head method test specimen using screw bending iron was produced and implemented to vertical tensile test, vertical compression test, and horizontal loading test. As a result, the test showed that it secured 1.28-3.62 times safety factors that are demanded from the design criteria for highway bridge.
