Uplift Resistance
Uplift resistance is the ability of a connection or structural assembly to resist forces trying to lift one part of the building away from another, usually due to wind suction.
In Detail
Load Path Context
Roof clips, post bases, holdowns, and anchor bolts often work together to provide uplift resistance. If one connection in the chain is weak, the whole load path is compromised.
That is why hurricane ties and foundation anchorage are so important even in projects that look simple from the outside.

Hurricane Ties
Hurricane ties are light-gauge metal connectors that tie rafters or trusses to the top plate and wall framing to resist wind uplift and maintain a continuous load path to the foundation.
Anchor Bolts
Anchor bolts secure sill plates, post bases, holdowns, and steel connectors to concrete or masonry and are a core part of the structural load path between wood framing and the foundation.
