Problem Statement

Interaction Diagram - Tied Reinforced Concrete Column Design Strength (ACI 318-19)

01 SketchUp model

02 ID Diagram

Develop an interaction diagram for the square tied concrete column shown in the figure below about the x-axis using ACI 318-19 provisions. Determine seven control points on the interaction diagram and compare the calculated values with the Reference and exact values from the complete interaction diagram generated by spColumn engineering software program by StructurePoint.
