【 摘 要 】

The issue of joints in masonry walls is often neglected and belittled from the structural point of view. It may even be said that the problem of joints is better investigated in terms of their thermal and acoustic insulation. Although such an approach can be justified to some extent in traditional construction (ceramic walls joined with traditional masonry bond), in case of joints with steel connectors such negligence can even lead to catastrophe. The issue of load transfer and co-operation between the crossing walls is very important for durability and safety of the structure. There is little experimental research in this topic worldwide. Designers do not have sufficient procedures and recommendations to design joints safely. Because of this void in the state of the art as well as the need to investigate the issue of masonry joints the authors decided to work on this subject. Experimental campaign is currently on going at the Faculty of Civil Engineering of the Silesian University of Technology in which joints in masonry walls made of AAC blocks. This paper presents the results of three specimens with traditional masonry bond. The tests were performed in a specifically constructed T-shaped test stand, with a web and a flange of ∼89 cm length. In addition to presentation of the differences in cracking and failure mechanisms as well as in load-bearing capacity, the authors attempted to describe the mechanism of each type of the joint.
