Intent 1:
To limit the probability of:
- failure of the ties,
- inadequate lateral load distribution, which could lead
to failure of the connection between intersecting walls, or
- inadequate bonding to mortar under lateral loads.
This is to limit the probability of
an inability to transfer lateral loads from masonry walls to intersecting
walls intended to provide lateral support, which could lead to inadequate
lateral stiffness, which could lead to an inability to resist lateral
loads or inadequate distribution of gravity loads, which could lead
to cracking or buckling.
Where transverse masonry walls support an environmental
separator, this is to limit the probability of deformation or cracking,
which could lead to the displacement or failure of required environmental
separation elements.
This is to limit the probability of:
- condensation,
- precipitation ingress,
- moisture ingress,
- excessive heat transfer,
- pollutant ingress, or
- compromised thermal performance of components intended
to resist heat transfer.
This is to limit the probability of:
- an inadequate control of temperatures in interior spaces,
drafts, relative humidity or water accumulation,
- the generation of pollutants from biological growth
or from materials that become unstable on wetting, or
- deterioration, which could lead to further compromised
integrity of environmental 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.
