Abstract:
A general analysis and design equation of reinforced concrete short and tied columns is proposed. This equation of failure surface represents both the strength interaction diagrams and failure surface of reinforced concrete sections under combined biaxial bending and axial load. Twelve analysis and design examples of columns under combined bending/biaxial bending and axial load are illustrated herein to provide an alternative analysis, review, and design of reinforced concrete columns under combined bending/biaxial bending and axial loadings.
