Maximum Load vs Column Width
Column Axial Load
P = A x Fc
Where A is the cross-sectional area and Fc is the allowable compressive stress. This applies to short columns where buckling is not a concern. For slender columns, the Euler buckling formula must be used to reduce the allowable load.
Example Calculation
6x6 wood column with 1,000 psi allowable stress.
- 01Area = 6 x 6 = 36 sq in
- 02Max load = 36 x 1000 = 36,000 lbs = 36 kips
- 03Note: actual lumber is 5.5 x 5.5 so use 30.25 sq in.
