Wind Uplift Design

In some cases wind loading can result in uplift loads on roof rafters. These uplift loads may result in stress reversals in TJI® roof joists and uplift reactions at bearing locations. The technical bulletin below explains the design consideration, such as changing the design of the roof and/or choosing specific strapping for the TJI® roof joists, to resist the forces caused by wind uplift.
