9.23.4.4.(3)

Intent 1:

To limit the probability of excessively long spans of beams or joists, which could lead to beams being unable to resist the additional weight of a concrete topping, which could lead to excessive deflection or failure.

This is to limit the probability of compromised structural integrity, which could lead to:

• the structural collapse of wood-frame construction, or
• where wood-frame construction supports or is part of an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of harm to persons.
