General Dowel Equations for Calculating Lateral Connection Values

The yield limit equations specified in the National Design Specification® (NDS®) for Wood Construction for bolt, lag screw, wood screw, nail, spike and drift pin connections represent a mechanics-based approach for connection design. This approach, which was incorporated in the 1991 NDS, permits the designer to determine effects of member thickness, member strength, fastener size, and fastener strength on lateral connection values for the majority of connections found in wood construction.
