Abstract:
In the revised CEB International Recommendations, the creep deformations of concrete are subdivided into reversible and irreversible strain components. In accordance with this new prediction method, constitutive creep laws are discussed here. The application of an algebraic stress-strain relationship for computing creep effects in cable-stayed concrete structures is shown. On the base of the creep function as formulated by CEB/DIN 4227, the "aging-coefficients" required for this algebraic approach are calculated and a numerical example is given.
