Determination of structural loads for the design of materials, components and assemblies that are subject to structural loads, such as those identified in Part 4 (see Clause 5.1.4.1.(3)(a) and Sentence 5.2.2.1.(2)).

This applies to building materials, components, assemblies and their interfaces described in Sentence 5.1.2.1.(1) that are installed in buildings to which Part 5 applies [see Sentence 1.3.3.2.(1) of Division A for application of Part 5].

This also applies to cladding assemblies installed on buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] where:

• the cladding assembly is not addressed in Section 9.27., or
• the cladding assembly does not comply with the prescriptive requirements of Section 9.27.

To limit the probability that incorrect loads will be used in the structural design of environmental separators, which could lead to an inadequate resistance to expected structural loads on required environmental separation elements, which could lead to vibration and deflection, which could lead to negative effects on the psychological well-being of persons.
