炭素繊維プレートによる鋼構造建物の長寿命化に関する研究(その3) : 化学プラント架構小ばり補剛の実施工例 Life Prolongation of Steel Building Using Carbon Fiber Reinforced Plastic Plate (Part3) : Rehabilitation of Secondary Beam in Chemical Plany Frame 玉井, 宏章 タマイ, ヒロユキ 高松, 隆夫 タカマツ, タカオ 原, 伸幸 ハラ, シンコウ 櫻庭, 誠 サクラバ, マコト 灰谷, 徳治 ハイタニ, トクジ 服部, 明生 ハットリ, アケオ Tamai, Hiroyuki Takamatsu, Takao Hara, Shinko Sakuraba, Makoto Haitani, Tokuji Hattori, Akeo 524.2 carbon fiber reinforced plastic plate bending rehabilitation case study application/pdf To enhance the usable life of existing steel buildings，a strengthening method with bonding continuous fiber reinforced plastic (FRP) plates has been developed by authors. Deep corrosion was observed in a chemical plant frame bleached in chemical atmosphere for a long term. 40% lack of beam rhickness was confirmed in the frame. The frame is appointed inan explosionprotection area，and a constructer cannot use fire during rehabilitation and repair. Therefore a strengthening method with bonding Carbon FRP was adopted.In this paper the progress of rehabilitation by bonding carbon FRP plates are introduced. Also，this paper reports the results of bending tests conducted on secondary beams in chemical plant frame before and after rehabilitation using Carbon FRP plates. departmental bulletin paper 広島工業大学 2006 VoR application/pdf 広島工業大学紀要. 研究編 40 103 109 AA11599110 13469975 https://it-hiroshima.repo.nii.ac.jp/record/719/files/kenkyuhen40103.pdf https://it-hiroshima.repo.nii.ac.jp/records/719 jpn
