Abstract:
The paper describes ma thema tically the deforma tional behavior beyond the ultimate strength level of a wide range of concretes under generalized static short-term loading conditions. This description complements that for the behavior prior to the ultimate strength level which has been the subject of previous publications. The derivation of the mathematical expressions has been based on the fundamental fracture mechanism of concrete, and it is shown that the stress-strain relationships predicted by the expressions correlate very closely with available experimental values.
