If a Versa-Lam® LVL beam is used as a joist and is "repetitive," a 4% increase is applied to the allowable bending moment. Each of the following requirements must be met:
- There are at least three adjacent members in the floor or roof system.
- The members are spaced at 24 inches on-center or less.
- They are joined by floor, roof or other load-distributing elements (plywood or OSB floor sheathing) adequate to transfer the design load to the Versa-Lam® joists.
