Abstract Autoclaved aerated concrete (AAC) masonry has excellent thermal insulation properties without needing an extra heat‐insulating layer. To keep the whole construction in a good thermal condition, the intersection of wall and slab had to be optimized for the heat transfer. The slab support becomes shorter and gets additional heat insulation on the outside. Because the final plaster needs a constant subsurface to prevent cracks, AAC‐fill units are covering the heat insulation. The short slab‐support leads to higher compressive stress and fill units could not be considered for the load transfer. But tests and numerical simulations have shown a significant participation. This paper presents a numeric parametric study with focus on fill units. A proposed equation gives the possibility to use a reserve of load‐bearing capacity. Finally, a calculation example is given.
