ABSTRACT
The mechanical connections, with the exception of moment splices, are not expected to transfer any moment from one element to another. There are two broad types of wood connections such as the mechanical connections that attach members with some kind of fasteners, and the adhesive connections that bind members chemically under controlled environmental conditions such as that seen in glued laminated timber. Post-frame ring shank nails are threaded nails. When the load along the fastener length is in compression, a washer or a plate of sufficient size is provided so that the compressive strength of the wood perpendicular to the grain is not exceeded. The shear-type connections rely on the bearing strength of wood against the metal fastener or the bending yield strength of the fastener. In a shear connection, load is perpendicular to the length of the fastener, and in a withdrawal connection, load is parallel to the length of the fastener.
