For split ring or shear plate connectors, moisture content limitations apply to a depth of 3/4" below the surface of the wood. Alternating Forces in Connections. Split ring and shear plate connectors are often viewed as specialty connections, and for this reason their use is covered only briefly. 13. Where a connection involves multiple shear planes and the connected members are at varying angles to each other, it is not possible to directly apply the joint strength equations given in 11.3 for toothed-plate connectors and in Section 11.4 for ring or split-ring connectors.. For this situation, the guidance given in EC5, 8.1.3(1), is that the resistance of each shear plane in the connection . Available in 2-1/2 and 4 diameters, split rings are used primarily in the assembly of clear span wood trusses for spans ranging from 20 to 250.

Traditional bolts, lag screws, nails, wood screws, timber rivets, split rings, and shear plates have been the recognized tools by timber engineers for their reliable record of performance. They are circular and are placed in pre-cut grooves produced by rotary cutters. Shear plate timber connectors (also called timber washers) are round, malleable iron discs that are inserted in precut grooves and are completely imbedded in the timber when in position, being flush with the surface of the timber. Ask Dan. Sort By: Filters: Reset All . 12.3.1.4 "Spacing" is the distance between centers of split ring or shear plate connectors measured along their connector axis . They are circular in nature with diameters ranging from 60 mm to 260 mm. For a joint using these connectors the strength model adopted assumes that when the connector is loaded parallel to the grain the joint strength will be the lesser of the strength due to embedment failure of the timber at the connector or shear block . fied in Tables .
