Intent 1:
To limit the probability that masonry adjacent to
chases or recesses will be unable to resist concentrated vertical
loads or to transfer horizontal loads to supporting elements, which
could lead to cracking.
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
- an inability to resist expected loads, which could lead
to:
- the excessive movement or deformation of walls, or
- the excessive deflection or vibration of floors.
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.
