| Abstract: | Concrete deterioration is becoming more and more serious with the age of large quantity of concrete structures growing. How to predict the remaining lives and what kind of effective measures should be taken have turned into urgent problems to solve. In this paper, an assessment criterion for remaining service lives of existing concrete structures is put forward based on the theory of reliability and economic optimization. And also, an optimum model to predict the remaining lives is provided. A numerical example about maintenance of an element indicates that there exist a most optimistic remaining service life and a most reasonable maintenance level for a concrete element. |
