International Building Code. Among the examples in this 32-page

loading, wood structural panel roofs and how to design a subdiaphragm.
This publication also offers suggestions for calculating deflection in
unblocked and non-uniform nailed diaphragms. Membership and Product

highest quality laminations are used only on the bottom). This
publication also includes design stresses and grade requirements for APA
EWS trademarked glulam, and how to specify glulam by stress
classification and end-use combinations. Corrosion-Resistant Fasteners For Construction is an APA technical note with fastener recommendations
for exterior siding, permanent wood foundations and fire-retardant
