Wood pallets are increasingly being used in drive-in racks and are often positioned for easy access with supports parallel to the outer stringers. The performance of these pallets is governed by the bending behavior of the deckboards as affected by the distribution of the load and the rigidity of the nailed joints. This report gives design formulas for calculating the short-term constant environmental condition bending stiffness and bending strength of three-stringer pallets used in racks. The formulas treat an arbitrary rigidity of the nailed joints and an arbitrary area of the top deck covered by a uniformly distributed, symmetric, and centrally applied load.
