Title:
Abstract:	Es wird anhand eines Rechenbeispieles gezeigt, dass die Größe von Zwangbeanspruchungen in Stahlbeton- und Spannbetontragwerken wesentlich von der zur Schnittkraftermittlung gewählten Berechnungsmethode abhängig ist und dass in Sonderfällen - z. B. zur Tragfähigkeitsbeurteilung älterer Bauwerke - eine nichtlineare Berechnung zur realistischen Erfassung von Zwangbeanspruchungen sinnvoll sein kann. Investigations on the Influence of Calculation Methods on the Dimension of Constraint Stresses in Reinforced Concrete Structures A calculation example shows, that the dimension of constraint stresses in reinforced concrete structures depends siginificantly on the calculation method used for the evaluation of stress-resultants. In particular cases - e.g. assessment of the load-bearingcapacity of older buildings - a nonlinear calculation is reasonable to have a realistic assessment of the contraint stresses.
