The relative role of creep coefficient and elastic modulus in concrete creep prediction models

Abstract: Creep deformation of concrete is often responsible for excessive deflections at service loads which can compromise the performance of a structure. National design codes therefore provide prediction models for the estimation of creep deformation. Such estimations are often presented as Specific Creep (Cc) which is defined as the creep strain per unit stress. The Cc predicted by a particular model is dependent on the ratio of the creep coefficient (φ) to the elastic modulus (E), both of which are empirically estimated by the relevant model..
