Column Design Verification by (N-M) Interaction Diagram


The purpose of this document is to outline the steps to verify reinforced concrete column design using the capacity curve, or commonly referred to as N-M (Axial-Moment) Interactive Diagram. The N-M Interaction Diagram will be derived using empirical formulas of concrete stress block. This is then compared to the same capacity curve generated by ProtaStructure column design, to verify the validity and adequacy of its column design.
