In part of the collaboration between Prof. Davorin Penava (UNIOS, Croatia), Dr. Matthias Roik (Leviat) and, Prof. Lars Abrahamczyk (BUW), further successful experimental tests were performed last week (week 46). In part of the experimental tests, data on the behavior of masonry panels under horizontal influences are obtained to validate numerical models in order to minimize damage in the future. The results are currently being evaluated and are expected to be published in joint publications in the coming year.
