9.15.2.3.(1)

Intent 1:

To limit the probability of the inadequate design of piers, which could lead to an inability to resist vertical building loads or lateral loads.

This is to limit the probability of:

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

For floors and elements supporting floors, this is to limit the probability of excessive deflection, which could lead to rough or uneven walking surfaces, which could lead to persons tripping or falling, which could lead to harm to persons.
