URS: Truss-to-Top-Plate Restraint

Uplift refers to the forces that can lift a structure. The forces are generated when high winds blow over the top of the structure, creating suction that can lift the roof. These uplift forces must be transferred down to the foundation to prevent damage. Several connections are required to create a continuous load path, starting typically with a hurricane tie connecting the roof truss to the top plates

For additional information, the Simpson Strong-Tie® High-Wind-Resistant Construction catalog offers a variety of options for resisting roof uplift forces.
