This paper presents the utilization of a new proposed approach for replacing the main flexural reinforcement concrete beams by steel checker plates of (6mm) thickness. Four reinforced concrete beams were cast and tested under two-point load. All beams had the same cross-sectional area of reinforcement and the dimensions of 210 cm in length, 35 cm in height and 25cm in width. The result show there was a reduction in crack load, yield load, and ultimate load of steel plate as compared to steel bar, Whereas increased with increasing cross-sectional area of the steel. Once, the increment in crack load and yield load of steel plate were 25.5% and 16,67% more than steel bar whereas the same increment was found in ultimate load for both steel bar and steel plate. The measured crack load and ductility for steel plate was 16.7% more than steel bar when increasing cross-sectional area of steel. The deflection past of failure for steel plate has a considerable deflection before failure than steel bar. Finally, the observations show cracks have been much wider and less in range for all steel plate samples in comparison with the steel bar.
