The recommendations in this publication apply to glulam beams bearing the APA EWS trademark. The mark appears only on beams manufactured by APA members and signifies that beams are produced to the requirements of American National Standards Institute (ANSI) Standard A190.1. This is the national consensus standard recognized by all model code agencies for the manufacture and trademarking of glulam.
The tables included in this data file include values for section properties and capacities, and allowable loads for simple span and cantilevered beams. The tables are based on an allowable bending stress of Fb = 2,400 psi for both Douglas-fir and southern pine.
These tables assume the compression edge of the beam is braced to prevent lateral buckling. For other bracing conditions, the beams should be checked for lateral stability.
For Douglas-fir, an allowable horizontal shear stress of Fv = 265 psi was used. For southern pine, an allowable horizontal shear stress of Fv = 300 psi was used. This standard is refererence in the 2012 IBC.
