1 General provisions 1.0.1 This standard is formulated in order to ensure the durability of concrete structures to fulfill the specified design working life and ensure the reasonable working life of engineering structures. 1.0.2 This standard is applicable to durability design of ordinary concrete structures and their members in house buildings, bridges, tunnels and other infrastructures and general structures in various natural environments. This standard does not take into account the degradation of structural performance caused by low-cyclic reversed load and sustained load, and is thus not applicable to structures made of light aggregate concrete, fiber concrete, and other special concrete types, nor the design of concrete structure durability in special corrosive environments such as high temperature and high humidity environment, microbial corrosive environment, electromagnetic environment, high pressure environment, stray current and the like in industrial production. 1.0.3 The durability provisions of this standard are the minimum requirements to make the structure fulfill the design working life with the specified assurance rate. The design may be appropriately improved according to the specific characteristics of the project, local environmental conditions and practical experience, and specific construction conditions. 1.0.4 In addition to this standard, the design of concrete structure durability shall also comply with those stipulated in the current relevant standards of China.
