Zyklische Schubversuche an Wänden aus Hochlochziegelmauerwerk.

Cyclic shear tests on walls made of clay block masonry Cyclic shear tests are a common method to assess the load‐bearing capacity and the deformation behaviour of walls under dynamic loads in the horizontal direction, such as those that occur during earthquakes. In the presented work, cyclic shear tests on 36 walls made of different types of masonry are described, the test results are shown and compared with calculated resistances according to Eurocode 6. After a list of the building materials used, the materials used and their dimensions are given for all examined walls. This is followed by a description of the experimental setups used at the institutes UTCB in Bucharest and ZAG in Ljubljana. The main part is the presentation of the measured values regarding achievable loads and drift values, as well as the determination of a bilinear approximation for each test. The envelope curves of the hysteresis loops of all experiments are then shown and compared. Finally, a comparison of the test results to calculated resistances according to Eurocode 6 is shown. With these investigations it could be shown that walls made of masonry have large drift capacities and that the assessment with the models of the Eurocode 6 delivers very realistic results. Furthermore, it could be shown, that conservative results are achieved when the resistance of masonry from concrete‐filled blocks is calculated with a composite stone strength, especially for walls with a higher degree of reinforcement.
