| Application | Application 1: Above-ground unreinforced masonry, nominally reinforced
masonry where vertical joints in adjacent courses are aligned [see Article 9.20.9.1.], loadbearing masonry of buildings of more than one storey in
regions where the spectral response acceleration Sa(0.2) is greater
than 0.55 that are reinforced in accordance with Sentence 9.20.1.2.(1),
and loadbearing masonry of 3-storey buildings in regions where the spectral response acceleration
Sa(0.2) is greater than 0.35 and less than or equal to 0.55 that
are reinforced in accordance with Sentence 9.20.1.2.(2), made with cellular
(foamed) concrete blocks, in buildings to which
Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application
of Part 9]:
Exceptions:
except as stated in Sentence 9.20.1.1.(2), which applies to buildings other than described above, or where the masonry
is designed for specified loads on the basis of ultimate and serviceability
limit states.

| Intent | Intent 1: To limit the probability of an inadequate resistance to
sulfate attack or stresses resulting from water absorption and freeze-thaw
cycling. For chimneys and fireplaces, this is to limit
the probability of excessive heat transfer, which could lead to the ignition
of combustible building components, which could lead to harm to persons.
