A tie, structural tie, connector, or structural connector is a structural component designed to resist tension.[1] It is the opposite of a strut, which is designed to resist compression. Ties are generally made of galvanized steel[2] Most ties have holes allowing them to be fastened to wood by nails. There are certain nails for certain ties.[citation needed] Screws, which usually have a lower shear strength than nails, are generally avoided.[3] Among the most common of these is the hurricane tie or seismic tie used in the framing of wooden structures.
[edit] Hanger
A hanger has a seat that a board, specifically a joist or girder, rests on. Hangers are most commonly used in floors, decks, and porches. If hangers are used the 'bowing' down[jargon] of floor joists and girders is less likely to occur. They also give added strength to the connection.
[edit] Hurricane tie
A hurricane tie is used to help make a structure (specifically wooden structures) more resistant to high winds, resisting uplift, racking, overturning, and sliding.[4] Each of the crucial connections in a structure, that would otherwise fail under the pressures of high winds, have a corresponding type of tie, generally made of galvanized or stainless steel, and intended to resist hurricane-force and other strong winds.
