Analytical Prediction of Ultimate Strength in Reinforced Concrete Columns
This paper describes the analytical method for predicting the ultimate strength of reinforced concrete columns using the true parabolic stress method of analysis. This methodology precludes the use of the current equivalent rectangular stress block, interaction formula and finite-element procedures to solve the ultimate strength of reinforced concrete section. This analytical method utilizes the concept of column capacity axis for equilibrium of external and internal forces which is a fundamental requirement in any structural analysis. It facilitates the calculation of the ultimate strength capacity of the column section at every depth of concrete section under compression and position of the column capacity axis. Variables considered in this method are the column section dimensions, concrete ultimate strength, fc', steel yield strength, fy, number, size, concrete cover, and spacing of reinforcing steel bars, and "θ", the inclination of the column capacity axis with the horizontal or the reference axis. Derived formulas for concrete and bar forces can be easily programmed in Microsoft Excel in customary or SI units.
