Research progress on the durability design and life prediction of concrete structures

This paper starts with the definition of concrete-structural durability.Then it presents that durability design method should be combined with the theory of Structural Life-Cycle Cost(SLCC) based on the survey of the recent durability design theories.Moreover,the current situation of evaluation and life prediction of durable concrete structures are summarized,which makes it necessary to determine a durability index reflecting service life and a dynamic life-assessment system.Last,several basic problems in this domain are brought forth, including definition of durability limit state for concrete structures under given environmental condition and usage requirement,determination of indexes and parameters representing the durability characters of materials as well as structures and establishment of theory for analysis of durability dynamic detection data.
