The connection(pile head) of pile supporting the building has conventionally been coupled(rigid coupling) by fixing method. Since the pile head was damaged in the earthquake occurred offshore Miyagi Pref. and the earthquake occurred in southern area of Hyogo Pref., the P/R pile research council was established, to develop the coupling method in which the pile head was not rigidly coupled. The P/R pile research council conducted each experiment, to acquire general assessment (BCJ assessment - FD0013) from the Foundation, Building Center of Japan ahead of industry in Mar.2001, and further tried to improve the performance and cost repeatedly, to acquire the additional assessment(BCJ assessment - D0013-02).
