Zum statischen System von Kellerwänden aus unbewehrtem Beton unter Erddruck

Static System of Earth Pressure loaded Basement Walls made of Non‐Reinforced Concrete Basement walls in housing are usually made of masonry or reinforced concrete. Both styles are more labor‐ and material‐intensive and therefore more expensive than basement walls without reinforcement. The required wall‐thickness of non‐reinforced walls is the most important reason for the general restraint. The design according to DIN 1045‐1 results in thicker walls compared to the design of masonry according to DIN 1053. The article illustrates the reason for the conservative design according to DIN 1045‐1 and its supposed static system in comparison to the developed design method deduced from finite‐element‐simulations. Hereby the wall thickness of non‐reinforced concrete walls can be reduced by using their ability of deformation.
