CONCRETE BEAMS REINFORCED WITH CONVENTIONAL STEEL BARS AND STEEL FIBRES: PROPERTIES IN STATIC LOADING

The effects of a combination of conventional steel reinforcement and steel fibre reinforcement on the flexural behaviour of concrete were investigated. It was found that the strength and ductility improvements brought about by the addition of fibres alone were much less than those which could be achieved by using conventional reinforcement. However, the combination of fibres and conventional reinforcement increased the flexural strength of the beams by 32-55 per cent compared to beams reinforced only with steel bars. Higher post-cracking rigidity was also obtained by the combined reinforcement. There was an increase in the number of cracks, but a decrease in their length and width. (Author/TRRL)
