Abstract
The strength analysis of columns with circular cross sections and evenly distributed reinforcement subject to an axial load and bending moment about one axis is considered. For such sections, a simple analysis technique is proposed to be applied in practice, which allows the basic formulas of nonlinear analysis to be reduced to formulas of strength of materials. The methodology is based on theoretically and experimentally substantiated assumptions, as well as on the introduced concept of the design strength of reinforced concrete. The proposed method is also grounded on modern deformation models using nonlinear stress–strain diagrams of materials. With the help of the accepted preconditions, the basic design dependencies were obtained. According to the developed method, examples of the area of reinforcement determination and definition of bearing capacity of eccentrically loaded members with circular cross section are given.
