Objective | OH4 Vibration and Deflection Limitation |
Attribution | |
Application | Application 1: Thickness of concrete in 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:
Exceptions:
except as stated in Sentence 9.20.1.1.(2), which applies to

Intent | Intent 1: To limit the probability of an insufficient thickness of
concrete in walls, insufficient bearing of supported walls, or eccentric loads
on the wall, which could lead to an inadequate resistance to lateral earth
pressure or an inability to support transverse or gravity loads, which could
lead to concrete cracking. 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.
