The size of rebar used in a reinforced cement concrete (RCC) beam typically depends on the design load, span, and structural requirements. For a simply supported beam of 17 feet, common rebar sizes range from #4 (1/2 inch diameter) to #6 (3/4 inch diameter) for main reinforcement, with additional smaller bars for stirrups. However, it is crucial to consult structural engineering guidelines or a structural engineer to determine the appropriate rebar size and spacing based on the specific loading conditions and design codes.
