Application
Application 1: 
Additional vertical reinforcement in unit masonry foundation walls made of concrete block that are required to be reinforced, are subject to lateral earth pressure, and are erected on average stable soils having an allowable bearing pressure of 75 kPa or greater, for buildings of wood-frame or masonry construction to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where:
  • the wind loads on the exposed portion of the foundation do not exceed 0.7 kPa, and
  • the height of finished ground above the basement floor or crawl space ground cover exceeds 2.0 m.
Exceptions: 
except as stated in:
  • Sentence 9.15.1.2.(1), which applies to foundations and footings for buildings erected on permafrost, and
  • Sentence 9.15.1.3.(1), which applies to detached buildings whose superstructure conforms to the requirements of the deformation resistance test in CAN/CSA-Z240.2.1, “Structural Requirements for Mobile Homes.”

Intent
Intent 1: 
To limit the probability that there will be an insufficient amount of vertical reinforcement in foundation walls exposed to high lateral earth loads or that the vertical reinforcement will be insufficiently embedded to transfer the lateral loads, which could lead to an inability to support transverse or vertical loads, which could lead to the cracking or displacement of the foundation walls.
This is to limit the probability of compromised structural integrity, which could lead to:
  • structural failure, or
  • where elements support or are part of an environmental separator, 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.
