General
The standard describes how the individual load cases should be combined for the respective design situations and which partial safety factors and combination factors should be applied.
The following design situations are distinguished in the standard:
- Permanent and transient design situation (basic combination) (ULS)
- Accidental design situation (ULS)
- Seismic design situation (ULS)
- Rare design situation (SLS)
- Frequent design situation (SLS)
- Quasi-permanent design situation (SLS)
Usage in Program
In RFEM or RSTAB, one design situation in the ULS (permanent and temporary) and three design situations in the SLS are already preset. The "Design situation type" setting allows you to select further situations.
The overview lists all load combinations with partial safety factors and combination coefficients that belong to a design situation. Thus, the design situation corresponds to an envelope that is used to determine the most unfavorable combination of all contained load combinations.
