(華僑大學 泉州 362021)［提要］ 從HFRP加固磚砌體雙剪試件的受力模型入手，從理論上分析試件的加固受力機理，推導抗剪承載力計算公式，并進行芳綸纖維復合材料(AFRP)加固磚砌體雙剪試件的驗證性試驗研究。結(jié)果表明，所推導的理論計算公式與試驗結(jié)果吻合較好。并得出影響AFRP布加固磚砌體抗剪極限承載力的主要因素是：有效發(fā)揮系數(shù)γ、摩擦系數(shù)μ和AFRP布條帶軸線與灰縫方向的夾角θ。［關鍵詞］ 芳綸纖維復合材料 磚砌體 加固 抗剪 抗剪承載力Shear resistant of Masonry Wall Double Shear Specimens Strengthened with AFRP/Huang Yihui，Wang Quanfeng，Yang Yongxin, Cai Zhihong (Huaqiao University，Quanzhuo 362021，China)Abstract:It takes from the force model of masonry wall double shear specimen strengthened with AFRP,and analyzes it"s reinforcement mechanism, then deduces the compute formula of the shear resistant, and takes a validation study of double shear specimen. The results express that the calculation formula has good accordance with the experiment results.It gets the main factors that influence the ultimate shear resistant of masonry wall strengthened with AFRP: valid exertive coefficientγ,coefficient of frictionμ, the included anger of the AFRP axis and the mortar joint θ.Keywords:aramid fiber reinforced plastics; masonry wall; reinforcement; shear; shear resistant
