Objective | OH4 Vibration and Deflection Limitation |
Attribution | |
Application | Application 1: Additional vertical reinforcement in unit masonry foundation walls made of concrete block that are required
to be reinforced, are subject to lateral earth pressure, and are erected on
average stable soils having an allowable bearing pressure
of 75 kPa or greater, for buildings of
wood-frame or masonry construction to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where:
Exceptions:

Intent | Intent 1: To limit the probability that there will be an insufficient
amount of vertical reinforcement in foundation walls exposed to high lateral
earth loads or that the vertical reinforcement will be insufficiently embedded
to transfer the lateral loads, which could lead to an inability to support
transverse or vertical loads, which could lead to the cracking or displacement
of the foundation walls. 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.
