The concept of using a collar or large cylindrical object to increase shear strength in wood construction has been around for several centuries in the forms of split rings and shear plates. [11] Shear plates provide a larger load-carrying capacity in shear than can be otherwise achieved by a bolt alone. [12]
A truss connector plate, or gang plate, is a kind of tie. Truss plates are light gauge metal plates used to connect prefabricated light frame wood trusses. They are produced by punching light gauge galvanized steel to create teeth on one side. The teeth are embedded in and hold the wooden frame components to the plate and each other.
