Abstract:
Describes an attempt to demonstrate that the behavior of an element of concrete in a structure cannot be described in terms of uniaxial stress-strain characteristics. Such a description not only unnecessarily complicates code provisions for ultimate limit state design but also is not theoretically correct. Design provisions should be based on an understanding of the causes of the observed structural behavior and this can only be achieved by considering the triaxial stress conditions that always develop within a structure under load. The validity of this proposal is supported by both analytical and experimental evidence obtained for reinforced concrete beams exhibiting flexural and shear modes of failure.
