This paper presents the results of an experimental investigation that evaluates the effectiveness of using Steel Fibre Reinforced Polymer (SFRP) sheets to confine small-scale plain concrete circular columns. Different parameters were investigated including: number of SFRP layers (1, 2, and 3) and concrete compressive strength (25, 30, and 35 MPa). A total of thirty-five circular specimens (150 mm diameter × 300 mm height) were tested and divided into three groups according to concrete compressive strength. In each group, two/three specimens were tested without wrapping for comparison purposes, and two/three specimens for each number of layers. The specimens were tested under monotonic concentric uni-axial compressive load. Results showed that SFRP confinement improved the performance of the concrete cylinders in terms of axial strength, stress-strain behaviour, and ductility.
