| Abstract: | Combined linear creep theory with brittle-elastic failure model, the recurrence formulas of calculating the temperature creep stresses in pouring blocks of concrete under construction are derived in this paper. The computer program is designed and a numerical example, is presented. The numerical results indicate that the present nonlinear model is satisfied. |
