9.8.10.3.(1)

Intent 1:

To limit the probability of the transfer of uplift loads from freezing soil to the underside of stairs, which could lead to the failure of the stairs, anchorage system or foundation wall, which could lead to an inability to support vertical building loads or lateral earth loads.

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

• structural failure, or
• for environmental separators or elements supporting environmental separators, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

This is to limit the probability of harm to persons.
