    The efficiency of strengthening of historic brick masonry walls for in-plane lateral loads with glass fiber grid reinforced mortar coating has been investigated. Two types of coating have been ... compared. In the first case, the coating consisted of diagonally placed glass fiber grid laid in fiber reinforced cementitious mortar, not anchored into the masonry. In the second, the coating has been strengthened at the ends of the walls with vertical strips of glass fiber grid, anchored into the masonry at the top and bottom ofthe walls with special carbon fiber string anchors. Significant increase in lateral resistance with regard to control walls has been observed in both cases, amounting to 1.7- and 2.3-times the resistance of the control walls, respectively. As a result of delamination of coating in the first case, no improvement in displacement capacity has been observed. In the second case, however, the anchors prevented the delamination and improved the displacement capacity of the walls by 50%.
