| Application | Application 1: In buildings to which Part
9 applies [see Sentence 1.3.3.3.(1) of Division A for application of
Part 9]:
- unreinforced masonry and masonry veneer walls, nominally reinforced
masonry where vertical joints in adjacent courses are aligned [see Article 9.20.9.1.], and loadbearing masonry elements
reinforced as required by Article 9.20.1.2. in regions where the
seismic spectral response acceleration, Sa(0.2), is greater than
0.35 [see Subsection 9.20.15.], where:
- the walls are not in contact with the ground
- the wall height above the foundation wall
does not exceed 11 m, and
- the roof or floor assembly above the first
storey is not of concrete construction,
- flat insulating concrete form walls not in contact with the
ground, where:
- the floor-to-floor height is not greater than 3 m,
- the buildings are not more than
2 storeys in building height and
they contain only a single dwelling unit, and
- the buildings are erected in locations
where the seismic spectral response acceleration, Sa(0.2), is not
greater than 0.4,
- mortar, grout, mortar joints, corbelling and protection for
unit masonry foundation walls [see Sentence 9.15.2.2.(2)],
- the installation of floor joists on foundation walls
of flat insulating concrete form wall units [see Sentence 9.15.4.3.(5)],
- cold joints in flat insulating concrete form foundation walls
[see Sentence 9.15.4.5.(3)],
- reinforcing around openings in flat insulating concrete form foundation walls [see Sentence 9.15.4.5.(4)],
- tying of masonry exterior facing to the top of foundation walls
that are reduced in thickness to permit the installation of such facing [see Sentence 9.15.4.7.(2)],
- corbelling of masonry foundation walls
supporting cavity walls [see Sentence 9.15.4.8.(1)],
- interior masonry foundation walls
not subject to lateral earth pressure [see Sentence 9.15.4.10.(1)], and
- masonry units in chimneys [see Sentence 9.21.4.1.(1)] and fireplaces [see Sentence 9.22.1.2.(1)] that are
not in contact with the ground.
Exceptions:
except as stated in:
- Sentence 9.20.1.1.(2), which applies to masonry and insulating
concrete form walls other than those described above, or where the walls are
designed for specified loads on the basis of ultimate and serviceability limit
states,
- Sentence 9.20.5.2.(3), which applies to the design of
steel angle lintels supporting masonry other than veneer, masonry and reinforced
concrete lintels, and masonry arches,
- Sentence 9.20.6.4.(4), which applies to masonry veneer
required to be individually supported by the backing material,
- Sentence 9.20.6.6.(1), which applies to slab facings and
precast concrete panel facings, and
- Sentence 9.20.9.5.(3), which applies to the securing of
masonry veneer that is individually supported by masonry or wood-frame backing.
