【摘要】 从HFRP加固砖砌体双剪试件的受力模型入手,从理论上分析试件的加固受力机理,推导抗剪承载力计算公式,并进行芳纶纤维复合材料(AFRP)加固砖砌体双剪试件的验证性试验研究。结果表明,所推导的理论计算公式与试验结果吻合较好。并得出影响AFRP布加固砖砌体抗剪极限承载力的主要因素是:有效发挥系数γ、摩擦系数μ和AFRP布条带轴线与灰缝方向的夹角θ。更多还原

【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 coefficient γ,coefficient of friction μ,the included anger of the AFRP axis and the mortar joint θ.更多还原
