Bond of GFRP strips on modern and historic brickwork masonry

In this paper the results of an investigation on the bond between GFRP strips and masonry surface both with modern and historic brickwork masonry are presented. Pull-push shear tests on bonded GFRP-to-brickwork masonry wallets were carried out considering the effects of mortar bed joints having different thicknesses. The experimental results indicated brittle failure due to delamination of GFRP strips; results were processed to evaluate failure load values, strain vs anchorage length diagrams, shear stress vs slip relationships experimentally and, energy fracture values. Finally, experimental results are compared with theoretical data obtained from theoretical models.
