Intent 1:
To limit the probability of:
- lintels that are inadequate in size or have an excessive
span, which could lead to the excessive deflection or failure of lintels,
which could lead to the cracking or structural failure of masonry
veneer over openings, or
- an inadequate bearing area between lintels and supported
masonry veneer, which could lead to shear or compression failure of
masonry veneer.
Where masonry construction is required to provide fire resistance,
this is to limit the probability of compromised fire resistance of
the assembly, which could lead to harm to persons.
