Übersicht

Es werden Grenzen für die Spannungen ausgerechnet, die in beliebigen Querschnitten eines Tragwerkes (z. B. in einem durchlaufenden Balken oder in einem Fachwerk) entstehen können, wenn nichtelastische Dehnungen begrenzter Größe aber unbekannter Verteilung auftreten. Als Beispiele werden ein durchlaufender Balken mit zwei Feldern sowie ein Fundamentrahmen durchgerechnet, um die Einzelheiten des Berechnungsganges zu zeigen.

Summary

Bounds are obtained on the stresses that can develop at an arbitrary section of a structure (such as a continuous beam, or a rigid frame) by anelastic strains of unknown distribution but bounded magnitudes. Examples of a continuous beam with two equal spans, and a portal frame are worked out in detail to illustrate the procedure.
