Abstract:The importance, ultimate principle and qualitative design method for the durability design of concrete structures were emphasized. According to the revised standard, the environmental category of durability, the requirements to durability of concrete material performance, the technical measures for preventing material degradation, the method for extending the design working life, the inspection and maintenance requirements of period of use were introduced. It could help designer understand and carry out the durability design of the revised standard.

Keywords:concrete structures; durability; design
