An accurate estimation of creep strains is mandatory to maintain the stability and integrity of concrete structures. Different parameters and conditions affect concrete creep predictions more precisely the relative humidity. To study its effect, a large database coming from international laboratories and research centers was applied to compare the experimental measurements to the theoretical values predicted by Eurocode 2 model. An inaccurate estimation was detected; therefore, an amelioration of the Eurocode 2 model was elaborated according to the relative humidity parameter. These calculations allow to predict accurately concrete creep and to avoid prejudicial consequences in structures due to creep phenomenon.
