Oct 31,2006·I'm particularly interested in nailed and bolted connections but I guess screwed connections would be good too.I know it is all in the NDS but I have a hard time decifering which mode will apply and I hate to calculate each different equation to figure out which one is the controling one.Any good references for this would be appreciated.Revisiting Spanning the Gap - Simpson Strong-Tie Technical Report 12,General Dowel Equations for Calculating Lateral Connection Values,is published by the American Wood Council.Technical Report 12 TR12 has yield limit equations that allow a designer to account for a gap between the main member and side member of a connection.Shear Value for Drift Pin in 8x8 column - Wood design and May 15,2009·Probably the best place to start is with the General Dowel Equation for Calculating Lateral Connection Values. I went through those god-awful General Dowel Equations and came up with a controlling Yield Mode IV,P = 4087 lb. This could help prevent any lateral splitout of the 8X8 side from the lateral bearing of the dowel.Mike McCann
