Novel graph for an appropriate cross section and length for cantilever RC beams

Abstract Whether the design is done manually or by software, designer will have difficulty choosing economic and strength cross section. The designer, in this case, either relies on their experience resorts to method of trial error. Especially for Cantilever beams with a long span as result risk deflections, it exposed. current theoretical study was performed rectangular concrete sections different dimensions subjected uniformly distributed loads. Based previous study, are reinforced specific reinforcement ratio. Through an algorithm, Python 3.4 output file, permissible deflections each section were calculated according ACI 318M-19. Finally, authors could draw graph choose appropriate required beam length less time effort.
