Figure 5.6 shows the results 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).
Přiřazeno ploše č.
This column shows the numbers of the surfaces where the governing points are located.
Bod č.
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).
Point-Coordinates X/Y/Z
The three columns show the coordinates of the governing FE nodes or grid points.
Zatěžování
Column E displays the load cases, load combinations, and result combinations whose internal forces lead to the greatest ratio for the respective serviceability limit state design.
Symbol
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 example.
The symbols have the following meaning:
| Typ | 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) |
Navržená hodnota
This column displays the values that are governing among all examined surfaces for the serviceability limit state designs.
Mezní hodnota
Mezní hodnoty se stanovují z normových předpisů a ze situace zatížení. The determination of limit values is described in chapter 2.6.4.
Využití
Column J shows the ratio of the existing value (column G) to the limit value (column H). Ratios greater than 1 mean that the design is not fulfilled. Políčka s hodnotami jsou částečně podbarvena. Délka barevného pruhu přitom odpovídá míře využití průřezu.
For the serviceability limit state design, not all check types have to be fulfilled (see explanation in Figure 3.11).
Poznámka
Poslední sloupec odkazuje na nezměřitelné body nebo poznámky, které se objevily během výpočtu. Čísla jsou blíže vysvětlena ve stavové liště.
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.
