SHEAR STRENGTH OF STEEL FIBER REINFORCED CONCRETE BEAM WITHOUT STIRRUPS

In the present dissertation work, an attempt is made to investigate shear strength and ductility of fiber reinforced concrete beams by using hooked steel fiber without stirrups and the semi-empirical equations proposed by authors in past years, are compared to find which equation holds accurate results. For this investigation, the test beam specimens of 125 mm in width, 250 mm in depth, and 1150 mm in length are cast and steel fibers are varied from 0.5 % up to 2 % volume fraction. The longitudinal steel is kept constant, while shear span-to-depth ratio (a/d) is varied in the range 1, 1.25, and 1.5. All the beam specimens are tested under two-point loading up to failure, and failure load, first crack load, and central deflection are recorded concisely and precisely.
