バーリングシァコネクタを用いた鋼管杭頭接合部の 弾塑性変形性状に関する実験的研究

摘要

近年，コンクリート杭が多く採用される中，鋼管杭および外殻鋼管付きコンクリート杭（SC杭）の使用が増加傾向にある.その理由の1つに，両者は剛性が大きく ，変形性能が期待できるため，鉛直荷重に 限らず，地震荷重のような水平方向からの外力に対しても優れた耐震 性能を発揮できることが挙げられる.%The present problems in pile head joints are roughly divided into two types as follows: 1) The workability of field welding and reinforcing bar arrangement work by the conventional method of construction is poor. 2) The dvelopment of the techniques for high strengthening in this part is delayed and no rational designing method has been established. In this research, in order to redpond to these problems, a pile head joint using a burring shear connector was devised. In this paper, the outline of the pile head joint that was invented is introduced, and the experiment for the purpose of verifying its structural performance and the discussion of experimental results are described.
