AbstractThe 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.
