  • Seismic strengthening of brick masonry walls with composites [Elektronski vir] : an experimental study
    Tomaževič, Miha ; Gams, Matija, gradbeništvo ; Berset, Thierry
    The efficiency of strengthening of brick masonry walls for seismic loads by application of different types of composite-reinforced coating, such as GFRP grid/fabric, CFRP fabric in either ... cementitious mortar of epoxy resin matrix, and CFRP strips, has been investigated. 24 walls have been tested as vertical cantilevers by subjecting them to constant pre-loading and cyclic in-plane lateral load reversals. Failure mechanism was characterized by delamination ofcoating or strips, which pulled off the masonry and buckled as soon as compression of the damaged masonry took place at repeated lateral load reversals. As a result of delamination, sudden resistance and stiffness degradation took place, leading to collapse of the walls. Whereas improved lateral resistance has been observed in most cases, adequate anchoring of coating was needed to improve the displacement capacity.
