July 2024, Birmingham N2 - With increasing thermal insulation requirements and resource-efficient construction methods, demands on building exterior walls are rising. Monolithic exterior walls, devoid of additional insulation, require meticulous planning and execution of the exterior wall-floor joint. Besides addressing building physics, fire safety, and sustainable construction, this detail must meet structural analysis standards. The joint’s load-bearing capacity hinges on both the masonry wall and slab loads. Masonry walls primarily bear loads from slabs and roof structures. However, slab loads induce rotation, adding bending stress to the masonry. Bending transmission depends on structural design, material parameters, and axial force, creating parameter interactions. To scrutinize various products and design variants regarding contact stiffness, load distribution, and stress concentrations, the Laboratory for Structural Engineering at the University of Applied Sciences (OTH) in Regensburg, Germany developed specific testing methods. These methods realistically capture load redistribution effects based on perforation patterns and quantify potential loadbearing reserves. Additionally, optimising design regulations based on results can accurately describe masonry’s load-deformation behaviour.

July 2024, Birmingham N2 - Masonry made of highly insulating clay units is a very common construction method, especially in multi-storey residential buildings. To apply this type of construction also in earthquake proven areas, the characterisation of strength and deformation properties under cyclic horizontal loads is essential. For this, a series of full-scale experimental investigations on the behaviour of walls made of thermally insulating clay unit masonry under combined loadings (N-M-V) were carried out in the Laboratory for Structural Engineering at the University of Applied Sciences Regensburg (OTH), Germany. The aim of the static-cyclic tests was to characterise the load-deformation behaviour and the failure mechanism under earthquake loadings. In conventional buildings, stiffening walls are loaded by vertical axial forces and horizontal in-plane loadings. The interaction with the concrete floor slabs leads to restraining effects in real buildings, which create counteracting bending moments. Accordingly, in the test, the loads were applied by a combined loading of bending moment and axial force. Digital image correlation documented deformations to identify failure mechanism. Results indicate that current design approaches according to DIN EN 1996-1-1 are on the safe side regarding the load-bearing capacity of the tested walls contain load-bearing capacity reserves. Based on the failure patterns from digital image correlation, it can be recognised that a strict separation of the individual failure types does not appear to make sense, as the ultimate failure of the test specimens was caused by a combination of several failure types.
