Calculation:
Designer/Checker:
   
Input:
 
(Note: All input Metric units are converted to English units for the equations below and then the output English units are converted back to Metric)
 
AWC 2012 NDS For Wood Construction 11.3.1, Yield Limit Equations For Lag Screws, Wood Screws, Nails and Spikes:
The following is for calculating lateral strength of a connection made up of lag screws, wood screws or nails and spikes using the yield limit equations.
   
   
 


Number of fasteners (N)
Dowel-type fastener diameter (D - in or mm)
Dowel bending yield strength (Fyb - psi or kPa)
Main member dowel bearing strength (Fem - psi or kPa)
Side member dowel bearing strength (Fes - psi or kPa)
Main member dowel bearing length (lm - in or mm)
Side member dowel bearing length (ls - in or mm)
Reduction term (Rd)
Load duration factor (Cd - for ASD only)*
Wet service factor (Cm)*
Temperature factor (Ct)*
Group action factor (Cg)*
Geometry factor (Cgeo)*
End grain factor (Ceg)*
Diaphragm factor (Cdi)*
Toe-nail factor (Ctn)*
Time effect factor (TEF - for LRFD only)
*Note if the factor is not required leave the default value set at 1.00.
