英文摘要	An accelerated life assessment method based on modified Coffin-Manson model was proposed.Experiments on accelerated life of concrete under temperature cycling were carried out.Relative mass and relative dynamic modulus of elasticity were taken as deterioration factors of competitive failure.The acceleration factor model of concrete under temperature cycling was established by using modified Coffin-Manson model.Estimated parameters of acceleration factor were calculated by linear regression.The acceleration factor value and failure life under normal temperature cycling stress were obtained, and the reliability function under normal temperature cyclic stress was obtained by using the best linear unbiased estimation.The results show that relative dynamic elastic modulus of concrete decreases with the addition of rubber particles, and relative dynamic modulus of elasticity plays a dominant role in concrete degradation under cyclic thermal stress, under normal temperature cyclic stress, the reliable life of normal concrete and rubber concrete specimens with 60% reliability is 8.69 and 12.83 a. © 2020, Editorial Board of Journal of Huazhong University of Science and Technology.
