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.
