This paper describes the influence of steel fibre distribution on the ultimate strength of concrete beams. The effect of delayed casting between the plain concrete and fibre concrete layers on the ultimate strength of concrete beams is also investigated. For the same amount of fibres used, strength of (partially) reinforced beams with fibres in the bottom layer only is about 25% more than that for fully reinforced beams. The presence of fibres in the compression zone does not significantly improve the beam strength. A delay in casting between the plain concrete and fibre concrete layers does not significantly change the ultimate strength of partially fibre reinforced concrete beams. © 1984.

Brief consideration is given to the uses of a quantitative measure of durability of concrete structural members. A classification scheme of structures, elements, and causes and effects is reviewed by the use of examples. Any quantitative measure of durability of in-situ structural members must be based on data gathered using non-destructive test methods. For any phenomenon such as cracking, corrosion or spalling which influences durability, three factors must be considered, a method of measurement of the phenomenon, the intensity of the phenomenon, and its distribution over the observed area.
