Abstract
The results of an experimental study aimed at seismic strengthening of brick masonry walls by the use of repointing and reinforcing bed joints are presented. Within the testing campaign eight walls were tested by cyclic shear. Two of the walls were used as control walls, whereas the other six walls were strengthened. Two kinds of mortar were used for repointing and steel and GFRP materials were used for reinforcement. In case of one wall, reinforcement was laid into a flexible polymer in order to distribute the stresses in the steel bar to a larger area. The tests indicate that repointing can be a very successful strengthening technique. Best results were obtained in case of repointing by mortar with low elastic modulus and steel reinforcement.
