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.
