AS 3600-2009 default load combinations
This section provides information on the default load combinations (technically, loading combinations) that RAM Concept creates when you start a new AS 3600-2009 file. The purpose and origin of each load combination are given. You can remove or modify any of these load combinations. You can also add load combinations. The load combinations are from AS/NZS 1170.0:2002 incorporating Amendments 1-5, unless noted otherwise.
RAM Concept uses loading types to determine the appropriate factors in some load combinations. For the short-term case the factor ψ will be equal to 1.0 for Live (Unreducible) and Live (Storage) and 0.7 for all other live loadings. For the long-term and combination cases, the factor ψ will be equal to 0.6 for Live (Unreducible) and Live (Storage), 0.4 for Live (Reducible), and 0.0 for Live (Roof). In the case of seismic load combinations ψ will be equal to 0.3 for Live (Reducible) or Parking loads.
