22 24 Notes:

1) Column is a single, one-piece member for dry-use applications only. DO NOT use this chart for multi-ply, built-up column applications. 2) Column is assumed to have adequate bracing in all directions at both ends. 3) Loads are calculated per the National Design Specification® for axial loads only. 4) For side-loaded columns, use appropriate design software or consult with a design professional. 5) Table assumes an eccentricity of 1/6 of the smaller column dimension. 6) Table assumes column bearing to be steel or concrete.
