The upper part of the window provides a summary of the governing serviceability limit state designs.
The lower part displays the intermediate results of the current FE node or grid point (of the entry selected above) including all design-relevant parameters.
You can expand the chapters with

Figure 5.6 shows the result window of an analytical serviceability limit state check. Chapter 5.7 describes the result windows that appear after a nonlinear serviceability limit state calculation has been carried out.
The method of check is defined in the Serviceability Limit State tab of window 1.1 General Data (see Figure 3.8).
This column shows the numbers of the surfaces where the governing points are located.
These FE nodes or grid points provide the maximum ratios for the required checks. The type of check is specified in column F, Symbol.
The FE mesh nodes M are generated automatically. The grid points G can be controlled in RFEM (see chapter 8.12 of the RFEM manual).
The three columns show the coordinates of the governing FE nodes or grid points.
Column E displays the load cases, load combinations, and result combinations whose internal forces lead to the greatest ratio in the respective serviceability limit state design.
Column F shows the type of the serviceability limit state design. In the analytical method, up to six design types are displayed. They are described in chapter 2.6.4 by means of an example.
The symbols have the following meaning:
| Type | Design SLS |
|---|---|
|
σc |
Limitation of concrete compressive stress (→ chapter 2.6.4.7) according to specifications in window 1.3 Surfaces (see Figure 3.19) |
|
σs |
Limitation of reinforcing steel stress (→ chapter 2.6.4.8) according to specifications in window 1.3 Surfaces (see Figure 3.18) |
|
as,min |
Minimum reinforcement for crack width limitation (→ chapter 2.6.4.9) according to specifications in window 1.3 Surfaces (see Figure 2.97) |
|
lim ds |
Limitation of rebar diameter (→ chapter 2.6.4.10) according to specifications in window 1.4 Reinforcement (see Figure 3.31) |
|
lim sl |
Limitation of rebar spacing (→ chapter 2.6.4.11) according to specifications in window 1.4 Reinforcement (see Figure 3.31) |
|
wk |
Limitation of crack width (→ chapter 2.6.4.12) according to specifications in window 1.3 Surfaces (see Figure 3.18) |
This column displays the values that are governing among all examined surfaces for the serviceability limit state designs.
The limit values are determined from the standard specifications and the load situation. The determination of limit values is described in chapter 2.6.4.
Column J shows the ratio of existing value (column G) to limit value (column H). Ratios greater than 1 mean that the design is not fulfilled. The length of the colored bar depicts the respective design ratio graphically.
Note
For the serviceability limit state design, not all check types have to be fulfilled (see explanation in Figure 3.11).
The final column indicates non-designable situations or notes referring to design issues. The numbers are clarified in the status bar.
The button shown on the left allows you to view all [Messages] of the current design case. A dialog box with an overview appears (see Figure 5.3).
Note
The buttons are described in chapter 6.
