Sentence 9.23.11.3.(4)

Intent 1:

To supersede the requirement for top plates stated in Sentence (1) and permit lintels with splices to serve the function of the top plates.

These minimum dimensions for metal splices, and wood splices and their fasteners are to limit the probability of discontinuous support at the ends of lintels, which could lead to lintels being unable to resist expected lateral loads, which could lead to the excessive deflection or failure of walls.

This is to limit the probability of compromised structural integrity, which could lead to:

• the structural collapse of wood-frame construction, or
• where wood-frame construction supports or is part of an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of:

• the space being unsuitable for its intended use,
• compromised operation of windows or doors, or
• damage to the building.
