- Description
- Only few experimental tests are available in the literature on bed-joint reinforced load-bearing masonry. These are performed on prototypes with different masonry typologies, often reduced scale and, in any case, only for a small number of combinations of slenderness, axial load and boundary conditions. This work presents the results
of an experimental campaign including in-plane cyclic tests on autoclaved aerated concrete (AAC) masonry panels with thin bed- and head-joints filled with glue-mortar. Some of the specimens are made of unreinforced masonry, whilst in other the masonry walls are reinforced by means of bed-joint flat-truss reinforcement only. Based on the results of these tests, complemented by specific tests performed on wallettes realised with the two
different construction techniques, a possible strength criterion is proposed. The results indicate that the inclusion of bed-joint reinforcement has the double effect of improving masonry resistance and displacement capacity, hence reducing damage.
