8. Column Interaction Diagram - spColumn Software

spColumn is a StructurePoint software program that performs the analysis and design of reinforced concrete sections subjected to axial force combined with uniaxial or biaxial bending. Using the provisions of the Strength Design Method and Unified Design Provisions, slenderness considerations are used for moment magnification due to second order effect (P-Delta) for sway and non-sway frames.

For this wall section, investigation mode was used with no loads (the program will only report control points) and no slenderness considerations using ACI 318-19.

Alternatively, the section and reinforcement arrangement can be imported to spColumn as an AutoCad file (.dxf).

The following figures show the section being imported to spColumn directly from AutoCad 2021.
