引張軸力領域を含む変動軸力と曲げを受けるノ之スリップ型露出柱脚の復元力特性と簡易履歴モデル

摘要

An anchor-bolt-yield-type exposed column-base showed many kinds of resisting mechanism subjected to tensile axial force and bending. Such resisting mechanisms have large effect on the hysteresis of restoring force characteristics, and that hysteresis curve was complicated. The authors proposed type exposed column-base had very simple hysteresis curve, which due to improving slip-phenomenon of anchor-bolt-yield-type exposed column-base. In this paper, an experimental study on proposed type exposed column-base sutfected to variable axial forces including tension and cyclic bending moment were carried out, and to proposed hysteresis model. The Allowing conclusions were drawn. 1) The restoring force characteristics was simply compare anchor-bolt-yield-type. 2) The hysteresis model showed good agreement with the experimental results for the axial force under the equation (12) value.%近年，大型振動台を用いた実験や複数の解析プログラム?実験システムを連結した評価法により，綱構造物の地震時全体挙動が明らかにされつつあるが，一方で部材レベルでは精確な挙動を評価するに至っていないものもある．本研究の対象である露出柱脚は，中低層綱構造物に多く採用されている一般的な接合形式であり，また．精確な挙動を評価できていない部材の一つである．
