Functional Statement:

To limit or accommodate dimensional change.

Objective:

OS2.3

 

APPLICATION:

Construction joints for carports or garages attached to dwelling units directly or by a breezeway, serving not more than one dwelling unit, for buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9], where both the main building and the garage or carport are supported by slab-on-ground construction.

INTENT:

To limit the probability that frost-related soil movement beneath the adjacent slabs-on-ground will be transmitted, which could lead to excessive stresses, which could lead to the cracking of slabs-on-ground supporting attached buildings, which could lead to an inability to support vertical building loads.
This is to limit the probability of:
  • structural failure, or
  • compromised structural integrity of elements supported by the slab, which could lead to the failure of environmental separation elements, which could lead to the deterioration of building elements.
This is to limit the probability of harm to persons.

To limit the probability that frost-related soil movement beneath the adjacent slabs-on-ground will be transmitted, which could lead to excessive stresses, which could lead to the cracking of slabs-on-ground supporting attached buildings, which could lead to an inability to support vertical building loads.
This is to limit the probability of:
  • pollutant ingress from the exterior, including soil gas, combustion products from parking garages, or particulates,
  • compromised thermal performance of components intended to provide resistance to heat transfer,
  • condensation,
  • precipitation ingress, or
  • the ingress of moisture from the ground.
This is to limit the probability of:
  • an inadequate control of the temperature of interior spaces or water accumulation, or
  • deterioration, which could lead to compromised integrity of environmental separators or of elements protected by the 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.

This is to limit the probability of:
  • movement of the slab or of elements supported by the slab, or
  • compromised integrity of elements supported by the slab, which could lead to the failure of required environmental separation elements, which could lead to the deterioration of building elements.
For floors and elements supporting floors, this is to limit the probability of excessive movement, deflection or vibration of floors, which could lead to negative effects on the psychological well-being of persons.
