The actual load-bearing capacities of highly thermally insulating plane clay unit masonry are to be quantified and compared with the calculated load-bearing capacities based on the unconfined stress-strain relationship and the linear-elastic, quasi-ductile and rigid-plastic material behaviour. In order to record also the deformations and compression at cross-section level directly in the load application area as well as the curvatures at system level, the deformations of all test specimens are documented by means of optical deformation measurement (digital image correlation). In this way, not only the load-bearing capacity but also, in particular, the stress resp. Strain distribution and stress redistributions as well as the experimental moment-curvature relationship can be quantified for the further analytical considerations and evaluations. Accordingly, it can be determined for all eccentric partial area loads that, regardless of the loading situation, higher load bearing capacities are achieved both compared to the calculated bearing capacity and based on a rigid-plastic material behaviour. Especially in the case of the loading situation at the bottom of the walls with partially supported floors, the activation of the unloaded cross-sectional zone at the load transfer can be shown very well based on the photogrammetrically determined cross-sectional compression. The decoupling initiated by the local discontinuity of the stress-strain state occurs only after the rigid-plastic cross-sectional bearing capacity is reached.}, language = {en} } @inproceedings{HofmannSchermerAmbergeretal., author = {Hofmann, Philipp and Schermer, Detleff and Amberger, Franziska and Meißner, Jonathan}, title = {Experimental investigation at the exterior wall-floor joint with partially supported slabs}, series = {18th International Brick and Block Masonry Conference : Proceedings of IB2MaC 2024 Volume 2, 21.-24.

The focus of this test series was on the influence of the nonlinear system behaviour at different axial force-moment combinations caused by the gaping of the horizontal joints as well as the contact zone between slab and masonry. With knowledge of the moment-rotation interaction as a function of the axial force of the wall, a numerical model can be developed with regard to the nonlinear system behaviour. Since the angle of rotation of the slab is of major importance in this respect, the structural design of a reinforced concrete slab is dispensed with in the test and replaced by a flexurally rigid solid steel bracket. This has the decisive advantage that the rotation of the steel bracket can be precisely detected by means of optical deformation measurement (digital image correlation) and directly assigned to the existing axial force-moment combinations. The evaluation of the tests has shown that the dominant nonlinear effect is essentially due to the gaping of the horizontal joints in the exterior wall-floor joint. During the test execution, the proportionality limit between the bracket moment and the bracket rotation could be successively increased with increasing load level regardless of the previous nonlinear system behaviour.}, language = {en} } @inproceedings{MeissnerSchermerAmbergeretal., author = {Meißner, Jonathan and Schermer, Detleff and Amberger, Franziska and Hofmann, Philipp}, title = {Experimental investigations on the influence of eccentric load application on the load bearing capacity of clay unit masonry walls}, series = {18th International Brick and Block Masonry Conference : Proceedings of IB2MaC 2024 Volume 2, 21.-24.

In addition, the influence of the increasing load inclination angle with decreasing test specimen slenderness is also shown. With regard to the wall compression tests under double-eccentric loading, the effects caused by the load inclination become obvious and lead to an average reduction of the load-bearing capacity of 41\% compared to the centric compression tests. Furthermore, an opposite effect can also be observed with regard to the generally known interaction between decreasing specimen slenderness and increasing load-bearing capacity. According to this, lower load-bearing capacities result with constant eccentricity and decreasing slenderness, so that a back calculation to a uniform slenderness ratio with the relevant normalisation functions is not possible. The reason for this is due to the linearly increasing load inclination angle and the resulting increasing shear stress within the transverse webs.}, language = {en} } @inproceedings{SchermerMeissnerAmbergeretal., author = {Schermer, Detleff and Meißner, Jonathan and Amberger, Franziska and Hofmann, Philipp}, title = {Numerical investigation for nonlinear internal forces at the exterior wall-floor joints}, series = {18th International Brick and Block Masonry Conference : Proceedings of IB2MaC 2024 Volume 2, 21.-24.
