Abstract

The effect of axial compression stress on the shear behaviour of High-strength Steel Fibre Reinforced Concrete T-beams was experimentally evaluated in this study. The main studied factors were the volume ratio of the steel fibre, the stirrups ratio and the flange width of the T-beam section. All beams were over-designed in flexure to ensure shear failure. The studied beams were tested under two third point loads. The results showed that applying axial compression stresses were effective in reducing the cracks widths and cracks propagation. Test results show the improvement in the stiffness,
cracking and ultimate strengths by adding fibre to beams without stirrups while in case of presence of stirrups, the effect of increasing the fibre volume ratio to 2%, was less than that of 1%. Also, it was found that the effect of adding stirrups on the beam properties decreases as the fibre volume ratio in the beam increases. Increasing the flange width did not affect the shear behaviour of the studied beams.
