| Abstract: | Bending damage concept is elucidated with the aid of Kachanov-Rabotnov's continuum damage variables, A bending damage theory is presented based on continuum thermodynamics for the concrete beam. In this theory, the bending damage variable is used as the bending stiffness deteriorate of the beam, and the bending damage criterions is obtained. |

| Keywords: | concrete beam bending properties irreversible process thermodynamics critical value / bending damage variable damage criterion |
