The SCC with palm kernel fibre were cast without web reinforcement. An experimental programme was designed for twenty fibre reinforced SCC beams incorporating bottom longitudinal steel bars. The beams were simply supported and subjected to 4 – point monotonic and cyclic loading tests. The variable parameters used were two different nominal coarse aggregate sizes 10 mm and 20 mm and different amounts of fibre reinforcements; 0, 0.25, 0.5 ,0.75 and 1 percentages by weight of cement. With the beams subject to loading, crack patterns were marked and cracking and ultimate loads were recorded. The deflection at all load points were also recorded. Test results indicated that the cracking behaviour with the addition of fibre was more effective in 10 mm nominal coarse aggregate size beams than the 20 mm nominal coarse aggregate size beams. This was because all the 10 mm nominal coarse aggregate size beams had the crack widths under service loads less than 0.3 mm. On the other hand, some of the 20 mm nominal coarse aggregate size beams recorded crack widths greater than 0.3 mm under monotonic and cyclic loading. The shear strength of the 10 mm nominal coarse aggregate size beams were observed to be more than the 20 mm nominal coarse aggregate size beams. In terms of the failure modes, all the beams, with the exception of one beam which failed by crushing at the support, failed by shear failure mode.
