多数配列アンカーボルトを有するノンスリップ型露出柱脚の復元力特性 Restoring Force Characteristics of Non-Slip-Type Exposed Column Base with Multi-Rows of Anchor Bolts 高松, 隆夫 タカマツ, タカオ 玉井, 宏章 タマイ, ヒロユキ 山西, 央朗 ヤマニシ, テルアキ Takamatsu, Takao Tamai, Hiroyuki Yamanishi, Teruaki 524.6 exposed column base anchor-bolt-yield-type restoring force characteristics slip-type multi-rows of anchor bolt application/pdf A non-slip-type exposed column base has been proposed by the authors, to improve slip phenomenon of an anchor-bolt-yield-type exposed column base by use of wedge device. Following advantages are obtained from usage of the wedge device. 1) No looseness at the column base occurs after anchor bolts yielding. 2) The column base can be designed as energy absorption damper in small earthquakes as well as huge ones. 3) The wedge device can be applicable for rehabilitation of conventional column bases because of easy installation in existing column bases. In this paper, the self-centering performance of the non-slip-type column base was examined by experiments on the column bases. The following conclusions were drawn. 1) The non-slip-type column base possesses the self-centering performance until the column base being in the elastic limitation of rotation. 2) The column base obtains the self-centering performance again, as the rotation returns the origin after increasing over the elastic limitation. departmental bulletin paper 広島工業大学 2006 VoR application/pdf 広島工業大学紀要. 研究編 40 137 146 AA11599110 13469975 https://it-hiroshima.repo.nii.ac.jp/record/716/files/kenkyuhen40137.pdf https://it-hiroshima.repo.nii.ac.jp/records/716 jpn
