Intent 1:
To limit the probability that the cavity wall's
centre of gravity will be too far outboard of its supporting foundation,
which could lead to excessive eccentricity of loads, which could lead
to cracking of cavity walls.
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.
