3.1.2 Serviceability Limit State
Serviceability Limit State
The serviceability limit state design depends on the results of the ultimate limit state design. Therefore, it is not possible to perform the serviceability limit state design alone.
This column lists all load cases, load and result combinations that have been defined in RFEM.
Normally, the actions and partial safety factors that are relevant for the serviceability limit state (SLS) design are different from the ones considered for the ultimate limit state. The corresponding combinations can be created in RFEM.
You can add or remove load cases, as well as load and result combinations as described in chapter 3.1.1.
For EN 1992-1-1, different limit values for the deflection can be assigned to the individual load cases, load and result combinations. The following design situations are available:
- Characteristic with direct load
- Characteristic with imposed deformation
You can change the design situation by using the drop-down list that can be opened by clicking .
With the [Details] button, you can access some settings for the individual design situations (see chapter 4.1.2).
The two option buttons allow you to configure whether you want to carry out the serviceability limit state designs according to the analytical or the nonlinear method.
In the following, both methods are described in detail.
