5.4 Serviceability Design Total
The upper part of the window presents a summary of the governing serviceability limit state designs . The lower part displays the intermediate results of the current FE node or grid point (that is, the entry selected above) including all design-relevant parameters. You can expand or reduce the chapters by clicking and .
Bild 5.6 shows the results window of an analytical serviceability limit state check. Chapter 5.7 describes the results windows that appear when a nonlinear serviceability limit state calculation is carried out.
The method of check is defined in the Serviceability Limit State tab of the 1.1 General Data window (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 displayed in the Symbol column F.
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 and result combinations whose internal forces produce the greatest ratio for the respective serviceability limit state design.
Column F shows the type of the serviceability limit state design. If you have selected the analytical method, this column will show up to six check types. They are described in chapter 2.6.4 by means of an example.
The symbols stand for the following types of checks:
|Type||Design of SLS|
This column displays the values that are governing of all 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 the existing value (column G) and the limit value (column H). Ratios greater than 1 mean that the design criterion is not satisfied. The length of the colored bar represents graphically the respective design ratio.
For the serviceability limit state design, it is not necessary that all types of verification are fulfilled (see explanation in Figure 3.11).
The final column indicates non-designable situations or notes referring to design issues. The numbers are explained 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).
The buttons are described in chapter 6.
