Contribution to the Calculation of Reinforced Concrete Circular Sections by Discrete Reinforcement

Abstract—The calculation of circular sections is not easy given the available reinforcements induces several unknowns in the equilibrium equations. The abacus of Davidovici, based on the principles of BAEL91 and EUROCODE2, assuming a uniform distribution of steel over the entire section, to determine the longitudinal reinforcement of these section bending made for this type of section limited in the case of a compressive axial load. In this study we propose a method for calculating circular sections under any combined loads (N, M), using discrete reinforcement able to take into account both the compressive and tensile axial load. This method is based on the interaction curves of reinforced concrete sections that may generate the number of steel bars necessary for the point representative of the combination load (N, M) is within the strength domain of the section.

Index Terms—Reinforced concrete, circular section, nonlinear calculation, combined bending.
