[F20-OS3.1] Applies to floors and elements that support floors.
Application
Application 1: 
Masonry piers with anchor bolts installed in their tops, in buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9]:
  • where the wall height above the foundation wall does not exceed 11 m, and
  • in which the roof or floor system above the first storey is not of concrete construction.

Intent
Intent 1: 
To limit the probability of insufficient depth of concrete or masonry for an adequate bond with anchor bolts, which could lead to inadequate withdrawal resistance, which could lead to an inability to resist expected wind loads, which could lead to overturning, lifting, sliding or excessive deflection of the superstructure.
This is to limit the probability of:
  • compromised structural integrity of the superstructure,
  • where piers support an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, or
  • an inability to resist expected loads, which could lead to excessive deflection or vibration of floors.
For floors and elements supporting floors, this is to limit the probability of persons losing their balance, tripping or falling, which could lead to harm to persons.
Intent 2: 
To direct Code users to Sentence 9.15.2.3.(4), which contains requirements for piers.
