In-Plane Behavior of Non-Structural Autoclaved Aerated Concrete Masonry Walls with Flexible Joints
BuildingsNowadays there is still a lack of requirements for the design of non-structural masonry walls. For the case of non-structural autoclaved aerated concrete (AAC) walls with perimeter flexible joints, experimental studies are scarce, and there are no ...
