This section provides information on the default load combinations (technically, loading combinations) that RAM Concept creates when you start a new CSA A23.3-04 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 the National Building Code of Canada 2005 unless noted otherwise.

The assumed importance factors for the default load combinations belong to the Normal Category. Importance factors are included in the load combinations, not the loadings. The corresponding load combinations will be generated incorporating the appropriate importance factor for the "normal" category. For importance categories other than "normal", the corresponding load combinations will need to be generated manually.
