Design reinforced concrete columns with confidence.
CSI COL delivers a comprehensive workflow for reinforced concrete column analysis, visualization, and reporting. It provides interactive capacity evaluation with detailed capacity points, design load checks, demand–capacity (DC) ratios, complete stress–strain and load–capacity results. The software automatically checks column slenderness, identifies sway or non-sway behavior in accordance with the selected design code, and applies moment magnification where required. Advanced response plots including moment–curvature and axial load–strain relationships support ductility assessment, plastic hinge evaluation, and performance-based design.
