ABSTRACT
The paper presents the results of experimental tests of joints of walls made of autoclaved aerated concrete (AAC). Different joint types were used to connect two walls: trusses, standards profiles and profiles with widened cross-section at the joint as well as polyurethane glue (foam) commonly used for bricklaying of masonry walls. 18 models were tested altogether in five series. The tests were performed on an original test stand in which shearing of wall joints can be realized with minimized bending. Morphology of cracking and mode of failure were analyzed; the load–deflection relationships of tested models and reference models with traditional masonry bonds were also compared. The tests showed differences in cracking and failure mechanisms as well as in load-bearing capacity of different joint types.
