9.15.4.5.(4)

Intent 1:

To limit the probability of insufficient reinforcement around openings or that reinforcement around openings will not be adequate to ensure a bond develops between the concrete and the reinforcement, which could lead to loads not being transferred across openings, which could lead to concrete cracking or the displacement of foundation walls.

This is to limit the probability of compromised structural integrity, which could lead to:

• structural failure,
• where elements support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements, or
• an inability to resist expected loads, which could lead to
  • the excessive deformation or deflection 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, or
• damage to the building.
