Design charts for channel shaped reinforced concrete short columns subjected to axial compressive load and uniaxial bending

Abstract

Eight design charts are presented for reinforced concrete short C-columns subjected to axial compressive load plus uniaxial bending. For design these charts can be used for determining the required column dimensions and amount of steel, while for analysis these charts can be used for estimating the loaded column capacity. Four examples are given to explain the use of design charts for both design and analysis, two of which are design examples while the other two are analysis. It has been shown by these examples that the new proposed charts are very simple to use in structural applications.
