9.29.5.8.(4)

Intent 1:

To limit the probability of inadequate support for gypsum board, which could lead to an inability to resist expected impact, gravity or lateral loads.

This is to limit the probability of the deformation or detachment of interior finishes, which could lead to:

• falling finishes,
• where interior finishes contribute to the required bracing or lateral support for studs, the buckling or racking of walls, which could lead to structural failure, or
• where interior finishes support or serve as required environmental separation elements, the excessive deformation, displacement or failure of such elements, which could lead to deterioration, which could lead to further compromised structural integrity.

Where walls support floors, this is to limit the probability of deflection or vibration of such floors, which could lead to negative effects on the psychological well-being of persons.
