The durability of reinforced concrete structures affects the safety and usability of the structure and hence design codes at home and abroad have made clear regulations on the durability of concrete structures. In order to analyze the similarities and differences in the concrete durability design of various countries，Chinese standards，British standards and American standards are studied in this paper to compare and analyze durability design content such as environmental exposure levels，concrete materials and structures. Combined with executed projects，the durability design of various standards is given. The analysis shows that the environment is classified into several categories based on various standards，and different durability designs are adopted based on different environmental categories，including concrete materials，concrete protective layer thickness，crack limiting measures，etc.
