| Abstract: | The analytical method of concrete bridges for the creeping Secondary inner force of creep has been described in this paper on the basis of the initial strain method and the principle of energy. The stiffness matrix and the force vector of the displacement method are derived, and the creeping effects of the structure under different construction conditions are presented and discussed. |
