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.

CM66, BAEL91

Extreme loads

CM66

Displacement loads

CM66

Accidental loads

CM66, Eurocode

Ultimate loads

BAEL91

Ultimate accidental loads

BAEL91

Earthquake loads

Combines load groups and uses factors according to the Eurocode.
