Shaping of AAC wall connections in the context of research and standards

<ns3:p>The article presents an analysis of masonry wall connections made of autoclaved aerated concrete (AAC) masonry units, based on experimental research and design standards. The theoretical section discusses the importance of both structural and non-structural connections in ensuring load-bearing capacity, stability, as well as thermal and acoustic insulation. Traditional methods – bonding, steel connectors, and reinforcement – are identified as fundamental and compliant with Eurocode 6. For non-load-bearing walls, simplified methods such as plaster connections or dovetail joints are also permitted. The article presents findings from experimental tests on 114 models, covering various connection methods and loading types. Traditional bonding demonstrated the highest load-bearing capacity and a gradual failure pattern. Alternative connections showed lower effectiveness, although locally widened metal plates improved performance. Practical conclusions were drawn and the need for further research and development of detailed design guidelines was identified</ns3:p>
