9.15.5.2.(2)

Intent 1:

To limit the probability of inadequate protection, which could lead to beam ends being exposed to water from rain or melting snow, which could lead to rotting or corrosion of the ends of beams.

This is to limit the probability of:

• compromised structural integrity, or
• where elements support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

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.
