ABSTRACT
Recently, construction method for precast superstructures of port piers is required to minimize offshore operation after pile driving. However, technical issues exist to connect precast concrete with steel pipe piles at the rigidity condition which is based on port design criteria. In this paper, “sleeve tube type” method is proposed to solve the connection problem of precast concrete and steel pipe piles without reducing workability. Mechanism focusing on the connection of precast concrete and steel pipe piles is discussed by the cyclic loading experiment. Next, a practical design method for the “sleeve tube type” was proposed. Finally, an example of filed application related to the “sleeve tube type” method is introduced to provide a better understanding.
