| Abstract: | The compressive fatigue experiments on concrete in hydraulic structure C15 are performed and the deformation modulus of the typical cycles is also tested.By analyzing the results of this fatigue experiments,it shows that the fatigue damage of concrete in hydraulic structure appears three-phase rules.The development model of fatigue deformation modulus,the development model of fatigue damage,and the instability criterion of fatigue damage are obtained for concrete in hydraulic structure,and research results ... |
