Abstract: Durability design is an important step of improving the reinforced concrete structure’s durability, and the numerical deterioration model of structure is the core of it. The utilization of numerical carbonation model enables the quantitative design of structure’s durability. By design examples, the design method based on carbonation life is illustrated.
