Steel pipe pile, which is used for the base of structures, need the reinforcing head method to prove enough dynamic performance. Currently there are various reinforcing head methods are used, but most of them have problems of structural complications and heavy charges. Thus, this study is to develop a reinforcing head method for steel pipe piles using hook type bending reinforcement, which can fix piles using nuts, and experimentally prove structural performances.
