Intent 1:
To limit the probability of discontinuity in mortar
joints at vertically aligned webs of hollow masonry units, which could
lead to:
- mortar joints of inadequate tensile and compressive
strength, or
- the inadequate containment of grout.
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.
