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 section lists all load cases, load combinations, 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 for the ultimate limit state. The corresponding combinations can be created in RFEM.
Load cases, load combinations, and result combinations can be added or removed as described in chapter 3.1.1.
For EN 1992-1-1, you can assign different limit values for the deflection to the individual load cases, load combinations, 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 list that can be accessed by clicking the button at the end of the input field.
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 perform the serviceability limit state designs according to the analytical or nonlinear method.
Both methods are described on the following pages.
