CHINESE CODE FOR DURABILITY DESIGN OF CONCRETE STRUCTURES: A STATE-OF-ART REPORT
On the basis of the final draft of Chinese national durability design code forconcrete structures,this paper reviews extensively the fundamental concepts,design approachand minimum requirements for durability design. Firstly,the environmental action,durabilitylimit state (DLS) and service life are introduced as the fundamental concepts for the codedrafting. With specific climate and environmental conditions in China,the environmentalactions are classified into five categories and six intensity degrees. Globally a deemed-to-satisfy approach is adopted in this design code with appropriate consideration given to model-based analysis. For corrosive environments,including atmospheric and chloride environments,the classification of environmental actions is refined in detail on the basis of the involvedmechanisms of deterioration processes. Then,the minimum requirements of durability designare formulated on concrete raw materials,concrete curing,crack control and environment-based durability indexes. Remarks are provided in the end for the remaining questions fordurability design.
