Shear tests on highly thermal insulating clay unit masonry walls with thin layer mortar / Schubversuche an hochwärmedämmendem Ziegelmauerwerk mit Dünnbettmörtel

The paper presents the results of a series of 6 shear tests on full scale highly thermal insulating clay unit masonry walls. The walls consisted of units with large voids filled with mineral wool with a thermal conductivity of &lgr; = 0,07 W/(m · K).
The aim of the investigations was the verification of the in-plane-shear resistance of this type of thermal insulating clay unit masonry in addition to the tests reported in [1].
The current design rules for clay unit masonry in DIN EN 1996-1-1/NA are rather conservative compared to the test results for thermal insulating units.
