Description
Summary:The selection of the most proper strengthening method/system with an assessment of its effectiveness is quite complicated in the case of masonry structures, mainly due to their huge diversity in materials. The most popular strengthening materials based on the composite fibres and are laid on the masonry wall using epoxy adhesives (FRP system) or mineral mortars (FRCM system). This article presents a comparison of external strengthening made using different glass-fibre-based materials on the behaviour of specific masonry walls. The walls are made of AAC blocks (Autoclaved Aerated Concrete), commonly used in rather low urban buildings or skeleton construction. As a strengthening material the GFRP sheets and two types of glass meshes are used. The walls are subjected to diagonal compression, which reflects the shearing of the walls. The scope of research describes cracking stage, shear capacity and analysis of the mode of failure of tested walls.
