Abstract
Shear behaviour in concrete materials is very well documented, for normal density concrete materials. In this paper results of various tests on low density concrete materials like aerated autoclaved concrete (in the following denoted aircrete) will be presented and analyzed for different combinations of reinforcement and for variable slenderness ratios. Theoretical approaches will be evaluated and compared with the test results of several test series. The load bearing capacity of shear reinforced aircrete is highly dependent on the anchorage and bond behaviour of the shear reinforcement. Recently developed formulas covering these areas will be presented and analyzed. The results presented show very consistent conformity with theory, both when considering mechanical anchorage of the reinforcement and when assuming pure bond for transferring initial forces between reinforcement and aircrete. Codes for designing prefabricated reinforced components of aircrete structures have adopted these recently developed approaches.
