炭素繊維プレートによる山形鋼圧縮材の接着補強設計式に関する実験的研究 DESIGN FORMULA FOR REHABILITATED ANGLE STEEL MEMBER USING CARBON FIBER REINFORCED PLASTIC PLATES 玉井, 宏章 タマイ, ヒロユキ 高松, 隆夫 タカマツ, タカオ 服部, 明生 ハットリ, アケオ 小澤, 吉幸 オザワ, ヨシユキ 山西, 央朗 ヤマニシ, テルアキ Tamai, Hiroyuki Takamatsu, Takao Hattori, Akeo Ozawa, Yoshiyuki Yamanishi, Teruaki Carbon fiber reinforced plastic plate Angle steel member Bonding Buckling Monotonic loading testes application/pdf The authors have developed a tensile force strengthening method using bonded carbon fiber reinforced plastic (CFRP) plate to enhance the life of existing buildings. A rehabilitation technique for compressive force strengthening as well as tensile force strengthening is required to enhance the strength and deformation of steel structure members. This paper reports the results of compressive loading tests on an angle steel brace before and after rehabilitation using bonded CFRP plates. These results show enhanced compressive force carrying capacity and deformation capacity as follows. 1) Although buckling tests showed enhanced flexural rigidity, there was no increment of axial stiffness. 2) An elastic buckling formula using the experimental flexural rigidity from a three-point bending test, gave a conservative evaluation of load carrying capacity. 3) Taking into count the contribution of CFRP up to the elastic limit strain of the steel member, its load carrying capacity could be evaluated from the formula of Design Standard for Steel Structures of AIJ. 4) The CFRP must be bonded over the full length of the angle member. 広島工業大学 2011 jpn departmental bulletin paper VoR https://it-hiroshima.repo.nii.ac.jp/records/886 40018724479 AA11599110 13469975 広島工業大学紀要. 研究編 45 165 173 https://it-hiroshima.repo.nii.ac.jp/record/886/files/kankyuhen45165.pdf application/pdf 4.9 MB 2023-03-30
