6.3 Filter for Results

The results windows of RF-CONCRETE Surfaces allow you to filter the results by various criteria. In addition, you can use the filter options described in chapter 9.9 of the RFEM manual in order to evaluate the design results graphically.

The possibilities provided by the Visibilities (see RFEM manual, chapter 9.9.1) can be used also for RF-CONCRETE Surfaces in order to filter the surfaces for the evaluation.

Likewise, you can use the Sections in the RFEM model or create new sections (see RFEM manual, chapter 9.6.1). This option allows you to evaluate the results more specifically. You can redistribute the reinforcement peaks that stem from singularities by using the smoothing function.

Find points

The results windows 2.2 and 2.3 (reinforcement) as well as 3.2 and 3.3 (serviceability) provide a search function for FE nodes and grid points. Click the button shown on the left (see Figure 6.1) to open the following dialog box.

Figure 6.7 Dialog box Find Point

First, enter the number of the surface manually, or click to select it graphically. Then, you can enter the number of the grid point or FE node , or select it in the list.

After clicking [OK], the current results window shows the results row of this point.

Sort results

Windows 3.1 and 3.2 show by default the results arranged by the maximum design ratios: The sorting conforms to table column J.

You can also sort the results by the existing values available in column G. For example, the greatest ratio of the deformation does not necessarily represent the maximum deformation because the limit values can be defined differently for each surface. Click the button to switch between these two types of results arrangement.

Filter points

The button shown on the left is available in the results windows 2.2 and 2.3 (reinforcement) as well as 3.2 and 3.3 (serviceability). It opens the following dialog box.

Figure 6.8 Dialog box Filter Points

In the Surface No. column, enter the number of the corresponding surface. Alternatively, you can select the surface graphically in the RFEM work window: Click into the input field, and then use the button.

The Points column offers several criteria for filtering. In addition to all designable or non-designable points, you can select only those points that are Governing : These points provide the maximum reinforcement areas or ratios for the respective type of check. Point numbers can also be User-Defined.

Show only designable or non-designable results

The two buttons shown on the left allow you to display only designable results or failed designs in the windows. Thus, you can hide, for example, failed designs due to singularities, or analyze the causes for design problems.

Filter results in work window

The reinforcements and design ratios can be used as filter criteria in the RFEM work window that you can access with the [Graphics] button. To apply this filter function, the panel must be displayed. If the panel is not active, select on the RFEM menu

      • View → Control Panel

or use the toolbar button shown on the left.

The panel is described in chapter 3.4.6 of the RFEM manual. You can set the filter for the results in the first panel tab (color spectrum ).

Figure 6.9 Filtering additional reinforcement with adjusted color spectrum

As shown in the figure above, you can set the panel's value scale so that only reinforcements greater than 1.00 cm2/m are displayed. The scale's color range is set in levels of 1.00 cm2/m; the maximum value of 8.00 cm2/m suppresses the effects of singularities .

The following chapter 6.4 describes how to adjust the value and color spectra to the diameters and spacings of the rebars.

For the display of grid point or FE node values in the graphics, the general control functions of RFEM are available. They are described in chapter 9.4 of the RFEM manual.

Filter surfaces in work window

In the Filter tab of the control panel, you can enter the numbers of selected surfaces to display their results in a filtered display. This function is described in chapter 9.9.3 of the RFEM manual.

Figure 6.10 Surface filter for reinforcement of floor slab and ceilings

In contrast to the visibility function, the model is displayed completely in the graphic. Figure 6.10 shows the reinforcement of the horizontal surfaces of a building. The remaining surfaces are shown in the model but are displayed without reinforcement.
