Abstract
This paper presents the development of formulas to estimate the creep strain of the reinforced concrete specimens. The experimental part of the work focused on the dispersion of shrinkage strain between reinforced concrete and plain concrete specimens, as well as the equilibrium condition between concrete tension and reinforcement compression. Based upon the experimental data and development formula, the creep strain and concrete age curves of the reinforced concrete specimens are drawn. Moreover, the characteristics of the creep strain are analyzed in detail. The creep strain formula can provide the important data and theoretic basis to “the code for design of concrete structures”（GB50010－2010）.
