Safe loads for wood columns.

Safe loads for Wood Columns - No.1 grade Douglas fir-larch:

Wood columns - safe loads

  • a kip is a non-SI unit of force - it equals 1,000 pounds-force
  • 1 kip = 4448 Newtons (N) = 4.45 kilo Newtons (kN) = 453 kgf

Example - Safe Loads with 4x4 Douglas Fir-Larch Column

According the diagram above - the safe loads for 4x4 Douglas Fir-Larch Columns with lengths 7.5 feet (2.5 m) are approximately 8 kips (35.6 kN, 3624 kgf).
