In-plane retrofitting of masonry structures by using GFRP strips in the bedjoints

Many unreinforced masonry structures were vulnerable in the past earthquakes and required retrofitting. The vulnerability of could solve by providing numerous retrofitting approaches. However, lack appropriate methods, which provide a solution for historical with lesser effects on their façade, is demanding. In this study, two one-third scale wall specimens made clay bricks tested under constant vertical cyclic lateral loading. consist an retrofitted GFRP strips. This study investigates seismic behavior walls before after using strips bedjoints. To purpose, various patterns have been studied simplified micro-modeling. results indicate that proposed technique improve strength stiffness considerable increase absorbed dissipated energy ductility content changes wall’s brittle failure to ductile one. method apply modern cement mortar has used as adhesive between layers.
