Durability in Design

This paper reviews the problems of durability and maintenance from two aspects. In the first part the size of the problem, recent developments and techniques for calculating the effects of design decisions are discussed. In the second part, the factors on which structural engineers must base their decisions on durability are examined for four particular problems: concrete in sulphate-bearing soils; steel reinforcement in concrete; the avoidance of inorganic ' growth ' on concrete; and the uses of corrosion resistant metals.
