| Abstract: | To begin with the mechanism of durability of concrete structures, the major factors that affect the durability are enumerated and suggestions given out according to the mechanism. After comparing in detail the durability of the main forms of pre-stressed concrete structure, it is concluded that the structural durability should be considered discretely when selecting structural forms. |
