An analytical model based on the experimental trend of the creep deformation of concrete in direct tension is developed. The model is calibrated for normal and high strength concretes and the results show close agreement with experimental data. The inclussion of the stress level is a unique feature of the model and presents a prospect for predicting concrete deformation for any regime of loading. The model confirm that the creep strain of concrete in tension are non-linear right frm the begining of loading therby ruling out the applicability of the principle of superposition The model presents a means for incorporating the nonlinearlity of creep into other predictive models of concrete.
