英文摘要	The concrete life prediction model does not accord with actual service conditions if only chloride ion, sulfate ion or carbonation are considered. To solve this problem, the corrosion current density, which reflects the steel corrosion, and the relative dynamic elastic modulus evaluation parameter, which characterizes the concrete damage, are taken as the marginal distribution function parameters. Then a life prediction model of Magnesium Oxychloride-Coated Reinforced Concrete (MOCRC) is established based on the Copula function. The results show that the Gumble-Copula function can predict the durability of MOCRC under the influence of two coupling factors, and the damage of MOCRC is about 20 000 d. The establishment of the Copula function life prediction model under the influence of two coupling factors provides a new research direction for the life prediction model under the multiple coupling factors. © 2020, Jilin University Press.
