| Abstract: | Uniaxial compress experiment and acoustic emission （AE） experiment were studied on concrete and steel fiber reinforced concrete. Firstly, relationship between mechanics parameter and acoustic emission parameter of concrete material were analyzed by using Dai formula, then the applicability and validity were proved. Secondly, conception of AE probability density function （PDF） was put forward, which was applied to evaluated damage of material, and the damage process was analyzed during the different load ratio. |
