Based on the factored axial loads and magnified moments considering slenderness effects, the capacity of the assumed column section (17 in. x 17 in. with 10 - #9 bars distributed on two sides) will be checked and confirmed to finalize the design. A column interaction diagram will be generated using strain compatibility analysis, the detailed procedure to develop column interaction diagram can be found in “Interaction Diagram - Tied Reinforced Concrete Column Design Strength (ACI 318-19)” example.
