Title:	Zuviel Stahl im Beton? - Stahlbeton - 120 Jahre Welterfolg auf der Basis eines falschen Ansatzes
Abstract:	Die Stahlbeton-Forschung und -Normung basiert auf der Stabwerksstatik. Damit werden die besonderen Eigenschaften des Baustoffs Beton nicht adäquat berücksichtigt und genutzt. Durch falsch geführte Hauptbewehrung werden Zugspannungen hervorgerufen, die durch zusätzliche Bewehrung (Bügel) aufgenommen werden müssen. An diversen Tragelementen wird gezeigt, wie durch die an den Zugtrajektorien orientierte Armierungsführung wesentlich kostengünstigere und umweltfreundlichere Bauwerke erstellt werden können. Too much steel in concrete structures? - Reinforced concrete - 120 years worldwide success on the basis of an incorrect approach The reinforced concrete research and standardization are based on the structural analysis of truss models. Thus, the special properties of the building material concrete are not taken into account and no adequate approach is found. Improperly performed main reinforcement causes tensile stresses, whereby additional reinforcement (stirrups) has to be included. At various structural elements is shown how much more cost effective and environmentally friendly buildings can be created by means of the reinforcement oriented to the tension trajectories.
