摘要
籍助于Kachanov-Rabotnov连续体损伤变量,阐明混凝土梁弯曲损伤概念,提出基于连续介质热力学的弯曲损伤理论.在弯曲损伤理论中建议用弯曲损伤变量β作为梁抗弯度劣变的力学度量,并得到了弯曲损伤判据。
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.
