Intent | Intent 1: To limit the probability of:
This is to limit the probability of an inability
to transfer lateral loads from framed walls to intersecting walls, which could
lead to inadequate lateral stiffness, which could lead to an inability to
resist lateral loads or inadequate distribution of gravity loads, which could
lead to cracking or buckling.
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.
