This Study is aimed to present a simplified approach enable to construction of a new design charts for hollow section reinforced concrete columns subjected to an axial compressive load and uniaxial bending. These design charts can be used directly in the analysis and design of hollow section columns. These charts can be used in design to determine the required amount of steel reinforcing in addition to the required column dimensions, while in the analysis by using these charts; the column load capacity can be estimated.
Two design examples are given to explain the use of the new design charts. It has been shown by these examples that the new proposed charts are very simple to use in structural design applications.
