Abstract
This report shows the results of an investigation by experimental study regarding the flexural loading capacity of slabs made of reinforced concrete and autoclaved lightweight concrete with vis holes for anchor. As a result, final failure patterns showed compressive failure of concrete of the compressive side for reinforced concrete slabs and shear failure for autoclaved lightweight concrete slabs. The flexural loading capacity of reinforced concrete slabs has shown almost similar with or without vis holes. On the other hand, the flexural loading capacity of autoclaved lightweight concrete slabs with vis holes was slightly smaller than that of without vis holes.
