Reinforced Concrete Columns - MCEER

Moment-Curvature Response of Shear-Critical RC
Column under Axial & Lateral (Shear) Loading
The flexural and axial capacity model for RC columns is used to derive an interaction
diagram which relates the axial load column capacity with its moment capacity at any
given time
