This paper presents the results of an experimental investigation on the shear response of slurry infiltrated fiber concrete (SIFCON) with and without dowel reinforcement when subjected to monotonically increasing shear loading. Specimens tested include plain slurry, plain concrete, dowel reinforced concrete, SIFCON, and dowel reinforced SIFCON. Several parameters were examined: two different volume fractions of fibers, two dowel reinforcement ratios, and two slurry compressive strengths. Special emphasis is placed on analyzing the contribution of steel fibers and dowel bar reinforcement to the strength, ductility, and energy-absorbing capacity of the composite. Findings indicate that dowel reinforced SIFCON has an outstanding response under shear loading. It has an ultimate shear strength of up to 35 MPa (5 ksi), and an energy-absorbing capability of up to 1,200 times that of plain concrete and up to 12 times that of dowel reinforced concrete.
