Abstract
In the context of the mechanical behaviour of FRCM (Fiber Reinforced Cementitious Matrix) composites as strengthening materials for masonry structures, an important issue is the evaluation of the shear transfer mechanisms between the FRCM material and the masonry. In this work a wide database of more than 500 experimental results of shear bond tests on FRCM-masonry specimens is collected. The data concern specimens made with different masonry supports and various FRCM materials. The data are subdivided into homogeneous classes. The occurrence of the different failure modes is studied and some considerations are assessed. Furthermore, the average peak shear stress and its variability is evaluated and a critical analysis is performed. Finally, a comparison among the failure tensile stress in the yarns obtained by i) the tensile tests on the dry textile meshes, by ii) the tensile tests on the FRCM specimens, and by iii) the bond tests on FRCM-masonry panel is provided.
