AS/NZS 1170.1-2002 Live Load Reduction

AS/NZS 1170.1 live load reduction is specified in code section 3.4.2.

When using AS/NZS 1170.1 to perform live load reduction, only live loadings with the "Live (Reducible)" type are reduced. Live (Storage) loadings are assumed to have loads greater than 5 kPa and are therefore not reducible per 3.4.2(ii).

Loading effects on one-way slabs are not reduced per 3.4.2(v).

For other member types, the reduction is calculated per the formula in 3.4.2(b).

Note: Section 3.4.2 actually defines an "application factor" not a "reduction factor" (reduction factor = 1 - application factor).
