This paper presents an experimental investigation on high strength steel fiber reinforcedconcrete (HSSFRC) deep beams behavior under monotonic static loads. Eleven simply-supported deep beams were tested and divided into three groups with different structural parameters. The studiedfactors were steel fiber volume fractions ( V f ), fibers aspect ratios ( l f /  f ), and shear span-to-depth ratios( a/d ). The mean compressive strength of concrete is 60 MPa. The main objectives were to study theeffect of fibers inclusion on response characteristics such as the shear carrying capacity, load-deflection curves, load-steel strain relationships, concrete surface strains, and failure modes. Thetesting results indicated that ( a/d ) ratio has a significant effect on the behavior of deep beams. Also,load carrying capacity, stiffness and strain ductility increase considerably with the increase of ( V f ) or( l f /  f ) ratio.
