Experimental and analytical studies on High Strength Concrete (HSC) columns subjected to biaxial bending are presented. The experimental work consisted of testing of twelve HSC columns. The primary test variables were load eccentricities about both the axes and the longitudinal steel ratio. All the columns were loaded to failure. The analytical work comprised development of a computer-based numerical algorithm to predict the strength of columns. The numerical analysis calculated the strength of the column in uniaxial bending separately about both the axes and applied the Bresler’s reciprocal load formula to predict the strength of the column in biaxial bending. The analysis applies to all grades of concrete. Good correlation between the test and calculated results is observed.
