Design of Round Reinforced-Concrete Columns
Publication: Journal of Structural Engineering
Volume 122, Issue 9
Abstract
A closed-form solution for the design and analysis of short circular reinforced columns is presented. The technique is based on transforming the components of the cross section, concrete, and steel, into an equivalent elastic material. The classical bending theory is used to develop an interaction formula that facilitates assessment of the performance of such columns. The solution provided accounts for nearly all the parameters that may contribute to the behavior of circular columns. Furthermore, no reference to the strength reduction factor is required in the course of locating the neutral axis. The problem is formulated to allow for the incorporation of strain hardening in reinforcement bars. The results obtained compared in a very satisfactory manner with that obtained using the equilibrium and compatibility approach. Flowcharts outlining the design, analysis, and rapid convergence of the technique are presented.
