Sentence 9.24.1.4.(1)

Intent 1:

To limit the probability that the performance and physical properties of steel screws, with respect to withdrawal resistance, pull-through resistance or shear strength, will fall significantly below expectations, which could lead to an inability to resist expected lateral and gravity loads.

For steel stud walls that support or are part of an environmental separator, this is to limit the probability of the excessive movement or deformation of walls, which could lead to the excessive deformation, displacement or failure of required environmental separation elements, which could lead to:

• pollutant ingress,
• condensation, or
• precipitation ingress.

This is to limit the probability of:

• an inadequate control of the temperature of interior spaces, drafts or relative humidity,
• the generation of pollutants from biological growth or from materials that become unstable on wetting, or
• deterioration, which could lead to compromised integrity of environmental separators.

This is to limit the probability of:

• negative effects on the air quality of indoor spaces,
• the inadequate thermal comfort of persons, and
• contact with moisture.

This is to limit the probability of harm to persons.
