Documenting Graphical Results of Reinforcement in RF-CONCRETE Surfaces

Technical Article

RFEM offers different options to display results graphically which have been determined in RF-CONCRETE Surfaces. This article gives an overview of these options.
  • Displaying by means of isobands
  • Displaying by means of isolines
  • Displaying numeric values
  • Creating graphics of large structures
  • Using display properties by all users

Displaying by Means of Isobands

Displaying isobands is preset in RFEM, but the value range and thus the color spectrum in the panel depends on the minimum and maximum value. The value range preset in the panel is not always useful for the documentation. As soon as minimum and maximum value vary significantly or if there are singularities in the results, the colored area important for the design may not be displayed.

By double-clicking the panel or clicking "Edit Value and Isoband Scales" in the shortcut menu, you can create user-defined value scales and color gradients which you can save as well. By using a user-defined color gradient, it is possible to define grayscales.

A specific feature, associated with RF-CONCRETE Surfaces and the panel, is the display of the required reinforcement by diameter and distance of rebar. Instead of displaying the reinforcement values in [cm²/m], the values are displayed as [Diameter-Distance Rebar]. The classification is possible in the details of the panel.

Displaying by Means of Isolines

In the menu bar, you can change the graphical display from isobands to isolines. The display of isolines corresponds to the display of level curves. The single lines can be labelled automatically or manually by using the Select function with the corresponding values.

In contrast to isobands, where one upper and one lower value is assigned to one color, each color of the isolines has only one value.

Displaying Numeric Values

The numeric values can be displayed for extreme values or for the values in the grid or FE mesh points. When displaying extreme values, you can control if they are displayed per surface, entire model or local extremes. By right-clicking "Of all local extreme values", you can define search parameters to display local extreme values. By clicking "Show only extremes", you can select if only the extreme values are displayed or if the extreme values are displayed in addition to the values in grid and FE mesh points. The "Transparent" display option shows the numeric value without frame. When the display option as grid points is selected, a corresponding point appears.

Figure 06 - Displaying Numeric Values

The points, which are displayed in addition when the option with transparent value display is selected, can be adjusted in color and size in the display properties at "Colors/Other/Text Bubbles". When displaying the values in grid points, the grid as surface property can be adjusted with "Edit Surface..." in the "Grid" tab.

Another display option is to only display numeric values. For example, it is then possible to display the values for each reinforcement side (top or bottom). You can select a corresponding group for this purpose. When this display option is selected, the values are displayed in the corresponding reinforcement direction.

Creating Graphics of Large Structures

If the structure which has to be documented is too large to display it on the selected paper size, it is recommended to divide it into single areas. It can be divided, for example, by means of a line grid or guidelines. The areas selected in the graphic window can be saved in the views. The selected results can be printed to the printout report together with the mass print and the saved views.

Using Display Properties by All Users

The settings selected in the display properties, such as font, color, text bubbles and position of the result values, are saved locally for one computer. If the same display properties should be available on another computer, you can save them in the Configuration Manager and import is possible as well.
