Load combination types
You can perform several load combination types which vary according to the building code you use.
Use the Load Combination Generation dialog box, or the Load Combination dialog box, to select the load combination types you want to create. The options are:
Combination type |
Description |
Applies to |
---|---|---|
Ultimate limit state (ULS) |
Combines load groups that occur persistently and transiently. Uses the partial safety factors of the ultimate limit state when combining loads. |
Eurocode, British, AISC (US) |
Serviceability limit state (SLS) |
Combines load groups that occur quasi-permanently. Uses the partial safety factors of the serviceability limit state when combining loads. |
Eurocode, AISC (US) |
Serviceability limit state – Rare (SLS RC) |
Combines load groups that occur quasi-permanently and rarely. Uses the partial safety factors of the serviceability limit state when combining loads. |
Eurocode |
Serviceability limit state – Quasi-permanent (SLS QP) |
Combines load groups that occur quasi-permanently. Uses the partial safety factors of the serviceability limit state when combining loads. |
Eurocode |
Normal loads |
Combines load groups and uses factors according to the French codes CM66 or BAEL91. |
