Tie (engineering)

[4] "Hurricane clip" has two meanings in building construction: Seismic ties are used to securely fix cabinets, bookcases, desks, appliances, machinery & equipment to walls and/or floors to constrain their movement during earthquakes.

When the strengthening is being done from the inside, the ideal connector to use is one that connects rafters or trusses directly to wall studs.

[8] A connector for connecting wall studs of two adjacent floors in a light frame building structure, the connector having a first attachment tab, a seat member, a diagonally slanted support leg, and a second attachment tab, all substantially planar.

A brace/tie across an interior angle of a wooden frame, forming the hypotenuse and securing the two side pieces together.

The clips provide a secure mount for wall panels, partitions, frames, cabinets, and more.

This helps keep walls from spreading due to the weight of the roof and anything on it, notably wet snow.

A sagging ridge is one clue that the home may lack adequate rafter ties.

Rafter ties form the bottom chord of a simple triangular roof truss.

Rafter ties are always required unless the roof has a structural (self-supporting) ridge, or is built using engineered trusses.
