The use of steel fibers to improve the mechanical properties of concrete has been the
ongoing interest in the research work. This paper deals with one such improvement in the
mechanical property of concrete, which is the shear strength. In this paper an attempt has been
made to study the improvement of shear strength of high strength concrete beams (70 MPa)
with different shear span to depth ratios (a/d = 1, 2, 3, and 4) and various dosages of fibers (0.4%,
0.8%, and 1.2% by volume of concrete), without shear reinforcement. The experimental work
revealed that steel fiber volume has different influence at different shear span to depth ratios
(a/d). The test results indicated an increase in the cracking shear resistance noticeably and
ultimate shear strength moderately.
