ABSTRACT
Effective damage prevention of structural elements is a basic maintenance activities. In particular, this applies to masonry structures sensitive to various types of ground deformations. The application of FRCM strengthening systems, which are based on the materials compatible with masonry substrate is a very good solution here. The paper presents an analysis of the impact of selected FRCM system on the behavior of walls made of AAC blocks. The strengthening in the form of basalt mesh was applied on the masonry surface - in two configurations - using pozzolanic reaction cementitious mortar. Test results showed a significant increase in shear capacity of the walls strengthened on both sides, as well as a desirable mode of failure with a safety margin after obtaining the load-bearing capacity. One-sided application of the system allowed for only a slight improvement in shear properties in comparison with unstrengthened walls.
