一定軸力下の露出柱脚に関する実験的研究 Experimental Study on Exposed Column-Base under Constant Column Axial-Force 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 restoring force characteristics axial-force anchor-bolt-yield-typ application/pdf An anchor-bolt-yield-type column base shows slip-type restoring force characteristics. The column base subjected to constant axial and cyclic horizontal forces shows more complicated characteristics. An experimental study on the column bases under constant axial-force and cyclic bending was carried out. The following conclusions were obtained from the loading tests: 1) Three types of resistant mechanisms of the column base under constant axial-force were classified to evaluate the strength and the elastic rotational stiffness. 2) In the case of axial-tension N＝0.3Ny,the restoring force characteristics of the column base were obtained combined all types of the resistant mechanisms. 3) In the case of axial-tension N＝0.6Ny, the restoring force characteristics became perfectly elasto-plastic curves without slip behavior. 広島工業大学 2008-02 jpn departmental bulletin paper VoR https://it-hiroshima.repo.nii.ac.jp/records/762 AA11599110 13469975 広島工業大学紀要. 研究編 42 113 119 https://it-hiroshima.repo.nii.ac.jp/record/762/files/42_113.pdf application/pdf 1.0 MB 2023-03-30
