Effect of types of fibres on the shear behaviour of deep beam with opening

Abstract

This paper discusses experiments on the behaviour of deep beams with and without opening in the styles of stainless-steel fibres under a two-point load test. Triple varieties of stainless steel fibre used (constant fibre fraction (1 percent) by volume of concrete, (straight, hooked and corrugated steel fibre)). In this analysis, the key parameters were the fibre forms and the influence of the opening on the behaviour. The results show that the steel fibres raise the first crack and final loads in both groups (first group without opening the second group with opening). Besides, an increase of (20.6 to 40.5) % in first cracking load for the first group and (36.4 to 56.7) % for the second group and an increase of (59.5 to 110.1) % and (20.2 to 28.8) % in ultimate load for first and second groups respectively.
