Abstract: Surrounding environmental actions are important factors which cause corrosion damages in reinforced concrete structures. With the appropriate environmental zonation documents, the durability and service life of an existing reinforced concrete structure in any region of China can be assessed easily, and the durability design of a new reinforced concrete structure can be carried out. Based on the environmental condition characteristics of engineering structures in China, a new method of environmental zonation for concrete structures was proposed. Firstly, environmental actions of concrete structures were classified into different categories.
Furthermore, zone division and grade determination for different kind of environmental actions were carried out on the map of our country based on the durability damage prediction models for concrete structures. Finally, the zonation results were further adjusted to take into account other environmental factors which were not considered in the original environmental zonation. Zonation of carbonation environment was taken as an example to illustrate the methodology of the environmental zonation for reinforced concrete structures in China.
