露出柱脚を有するノンコンプレションブレース付き架構に関する研究 A study on non-compression braced-frame with exposed column-base 高松, 隆夫 タカマツ, タカオ 山西, 央朗 ヤマニシ, テルアキ 玉井, 宏章 タマイ, ヒロユキ 竹本, 泰聖 タケモト, ヤスマサ Takamatsu, Takao Yamanishi, Teruaki Tamai, Hiroyuki Takemoto, Yasumasa non-compression brace exposed column-base anchor-bolt-yield-type resisting mechanism application/pdf Non-compression braces show perfectly elastic-plastic restoring force characteristics without both buckling and slip behavior because of wedge-device function. Those braces possess excellent energy absorption capability and slender members can be chosen as earthquake resistant braces. When strength of column bases is weaker than the braces, it is not clear that behavior of the column bases influences the restoring force characteristics of the braces in cyclic loadings. Experimental study on cyclic loading tests of non-compression-braced frames with exposed- type column bases was carried out to clarify resistant mechanism of the column base and cyclic behavior of the braced frame. The following conclusions were obtained from the experimental results: 1) The braced frames showed bi-linear-type cyclic curves in case of brace-strength less than von Mises yield condition of anchor-bolts; 2) The braces were yielding because of reduction of shear stress of anchor-bolts caused by friction of the base-plate and the foundation in case of brace-strength larger than von Mises yield condition of anchor-bolts. departmental bulletin paper 広島工業大学 2011 VoR application/pdf 広島工業大学紀要. 研究編 45 85 92 AA11599110 13469975 https://it-hiroshima.repo.nii.ac.jp/record/876/files/kenkyuhen45085.pdf https://it-hiroshima.repo.nii.ac.jp/records/876 jpn 40018724469
