Maximum Load vs Column Width
Formel
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.
Lösungsbeispiel
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.
Häufig Gestellte Fragen
When is a column considered short vs slender?
For wood, if the slenderness ratio (Le/d) is less than about 11, it is a short column. Steel columns use KL/r; below about 40 is considered short. Slender columns require buckling analysis.
What is the actual size of a 6x6 post?
Nominal 6x6 lumber actually measures 5.5 x 5.5 inches. Always use the actual dimensions for structural calculations.
