Out-of-plane behaviour of clay brick masonry walls retrofitted with flexible deep mounted CFRP strips and additional single-sided FRCM overlay

The deep mounting of CFRP strips to masonry using a flexible adhesive was developed as minimally-invasive and cost-effective out-of-plane seismic retrofitting technique for unreinforced (URM) buildings. Previous experiments on one-way spanning full-scale walls confirmed the significant added value lateral resistance displacement capacity Flexible Deep Mounted (FDM) retrofitted with respect masonry. This performance could be further enhanced by addition single-sided Fabric Reinforced Cementitious Matrix (FRCM) overlay FDM walls. purpose current experimental campaign primarily investigate both strip FRCM overlay. results proposed retrofit combination URM solely A cross section analysis non-linear linear material models used components proposed. model provided an overestimation moment that were high mid-span displacement. For additionally reinforced overlay, good approximation internal versus curvature mid span relationships.
