Sažetak
The numerical model for the analysis of in-plane creep behaviour of concrete, based on the correction of the modulus of elasticity in principal direction, for the current state of principal stresses, is presented. The elastic modulus correction is dependent on the current creep coefficient and the current elastic modulus as obtained from the uniaxial diagram of concrete in compression. The model’s accuracy was analyzed on appropriate laboratory and numerical examples of reinforced and prestressed concrete structures, using a computer program developed for that purpose.
