PROPOSAL OF RAKING PILE CONNECTION WITH PRECAST SUPERSTRUCTURE FOR PORT PIER

Abstract

 The authors have already proposed “Sleeve tube type” as a pile head connection which is suitable for precast superstructure of vertical pile pier. However, for the case of raking pile pier, which is also widely used as port pier for its high lateral rigidity, “Sleeve tube type” is difficult to be applied for the concern of lower rigid connection of precast concrete due to larger sleeve tube diameter. In this paper, the authors proposed another “Socket rebar type” as a new type of pile head connection for raking pile pier, and cyclic loading tests are carried out to confirm the rigid connection of pile connection for both methods. As a result, under test conditions with a raking angle of 10 degrees, “Sleeve tube type” was almost the same with conventional pile head connection, and “Socket rebar type” was better in terms of rigid connection and lateral rigidity.
