Objective

OP2 Structural Sufficiency of the Building

Attribution

Intent

Intent 1:

To limit the probability that any surcharge on the foundation walls will not be included in the design pressures, which could lead to the walls being unable to resist lateral pressure, which could lead to the cracking of foundations or building superstructures.

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

  • structural failure,
  • 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, which could lead to further compromised structural integrity, or
  • an inability to resist expected loads, which could lead to
    • the excessive deformation or deflection of walls, or
    • the excessive deflection or vibration of floors.

This is to limit the probability of:

  • the space being unsuitable for its intended use, or
  • damage to the building.

Intent 2:

To expand the application of Section 4.2. to walls supporting other than drained earth that are not constructed in accordance with Section 9.15.
