Abstract: This paper presents the basic principle for calculating the creep effect on R. C. bridges by deformation method. On the basis of the creep pattern of the aging theory further considerations associated with the effect on the delayed elasticity of the creep of cement concrete have been discussed furthermore. Various equations are derived and the degree of accuracy of computation by different methods through some examples are compared. It is concluded that the effect on the delayed elasticity must be considered.
