Attribution | |
Application | Application 1: Minimum width of concrete footings for foundations or loadbearing columns, for buildings to
which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9] with light wood-frame walls, floors and roofs, where the span of

Intent | Intent 1: To limit the probability of an insufficient bearing area
for footings, which could lead to compressive failure and excessive settlement
of underlying soil, which could lead to structural damage to the foundation
and the building, which could lead to an inability to support vertical building
loads or lateral earth loads. This is to limit the probability
of:
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.
