Shear Tests on Thermal Insulating Clay Unit Masonry Walls
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.
