Size effect of monotonically sheared masonry walls made of AAC masonry units
The paper presents results of shear tests on 13 walls made of autoclaved aerated concrete (AAC) masonry units. Four series of walls varying in length equal to l = 4.43, 2.95, 2.36, and 1.48 m, and an identical height of h = 2.43 m were made and tested. The thickness of all walls was identical and equal to t = 0.18 m. Compressive strength of material masonry units and mortar for thin joints was equal to fb = 4.0 N/mm2 and fm = 6.1 N/mm2. The wall compression strength (according to EN 1052‐1:2000) was fc,mv = 2.97 N/mm2 (fk = 2.48 N/mm2) and elastic modulus was Ecm = 2.040 N/mm2. Walls were tested at various initial compressive stresses perpendicular to the plane of support joints σc = 0.1, 0.75, and 1.00 N/mm2. Shear load was applied to the upper edge of walls in a monotonic manner, controlling the load increment. The morphology of cracking and the mechanism of destruction were analyzed. In addition, empirical dependencies were formulated to determine the effect of initial compressive stresses and the impact of wal thickness h/l.
