Extension of reinforcement beyond the edges of openings in non-loadbearing flat insulating concrete form walls not in contact with the ground, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where:

• the floor-to-floor height is not greater than 3 m,
• the buildings are not more than 2 storeys in building height and they contain only a single dwelling unit, and
• the buildings are erected in locations where the seismic spectral response acceleration, S_a(0.2), is not greater than 0.4.

Exceptions: 

To limit the probability that the reinforcement will not be sufficiently embedded to develop a bond with the concrete, which could lead to an inability to transfer the loads around openings in the walls, which could lead to an inability to resist transverse or vertical loads, which could lead to concrete cracking or the displacement of 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.
