Untersuchungen zur Schub-Druck-Tragfähigkeit von Mauerwerk aus kleinformatigen Mauersteinen

Investigations on the shear-compression-load-bearing-capacity of masonry consisting of small-format bricks. The load-bearing-capacity of masonry consisting of small-format artificial bricks with regard to a combined shear-compression load is a complex and not conclusively researched topic. Due to the practical relevance of this topic and for reasons of sustainability, research must therefore be carried out continuously in order to be able to close the existing gaps in knowledge. Intensive and extensive theoretical and practical tests have therefore been and are being carried out at the Chair of Concrete and Masonry Structures at the Technical University of Munich, with the aim of systematically analyzing and evaluating the load-bearing and damage mechanisms of small format masonry for a wide variety of load scenarios and parameter combinations. In order to minimize the experimental effort, a methodology was created that enables the realistic representation of the load-bearing behavior of small-format masonry in an efficient manner on the basis of predominantly small-scale tests. With the help of the so-called unit-cell method it was possible to derive statements on the biaxial load-bearing capacity of historical masonry with regard to the influence of the normal stress level and the angle of inclination of the resulting diagonal force.
