Intent 1:
To limit the probability of:
- excessively rapid corrosion, which could lead to the
excessive deflection or structural failure of lintels, or
- the accumulation of corrosion by-products between lintels
and masonry, which could lead to compressive stresses.
This is to limit the probability of:
- compromised structural integrity of masonry construction,
- where masonry construction is part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to deterioration, or
- in assemblies exposed to moisture or the exterior, damage
and deterioration.
For floors and elements supporting floors, this is to limit
the probability of excessive movement, deflection or vibration, which
could lead to negative effects on the psychological well-being of
persons.
