ABSTRACT
The chapter presents results of shear tests on monolithic external walls with reduced support length under static-cyclic and pseudo- dynamic loading. Monolithic external walls are commonly made of thermal-insulating clay blocks that do not require an additional external thermal insulation for example External Thermal Insulating Composite Systems. A comparison with the design values according to DIN EN 1996 and the respective German National Annex, shows a significant underestimation of the shear-resistance of monolithic clay masonry walls. In case of long walls with large vertical loads DIN EN 1996-1-1 overestimates the shear resistance significantly. The calculations according to DIN EN 1996-1-1/NA leads to a better fit with the test results. In case of short walls and/or long walls with low vertical loads the exclusive use of the equation for bending failure leads to sufficiently precise results. The consideration of the for the shear resistance leads to an underestimation of the test results.
