Recently, construction method for precast superstructures of port piers is required to minimize offshore operation after pipe 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 fixation of precast concrete and steel pipe piles is discussed through the cyclic loading experiment. Next, conducted a three-dimensional nonlinear finite element analysis on cyclic loading experiment of “sleeve tube type”, examined the effect of shear key, the insert length of steel pipe pile into sleeve tube, and discussed the stress transmission mechanism of the connection. Furthermore, a practical design method for the “sleeve tube type” was proposed. Finally, points to be noted both the method for precast superstructures and applying the “sleeve tube type” are shown.
