6.3 Filter for Results
The result windows of RF-CONCRETE Surfaces allow you to select the results according to 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 options provided by the Visibilities (see RFEM manual, chapter 9.9.1) can also be used for RF-CONCRETE Surfaces in order to filter the surfaces for the evaluation.
You can also use the Sections in the RFEM model or create new ones (see RFEM manual, chapter 9.6.1), which allow you to selectively evaluate the results. By using the smoothing function, you can redistribute the reinforcement peaks that stem from singularities.
The result 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.
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 result row of this point is set the current window.
By default, the windows 3.1 and 3.2 show the results arranged by the maximum design ratios: The decisive factor for this is table column J.
You can also sort the results by the existing values available in column G. The greatest ratio of the deformation, for example, does not necessarily have to be the maximum deformation because the limit values can be defined differently for each surface. You can use the button to switch between the two types of arrangement.
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.
In the Surface No. column, you can enter the the desired surface number or select it graphically in the RFEM work window: To access this function, click into the input field and use the button.
The Points column provides several filter criteria. In addition to all designable or non-designable points, you can select only the points that are Governing: These points provide the largest reinforcement areas or ratios for the respective types of check. Point numbers can also be User-Defined.
The two buttons shown on the left allow you to only display designable results or failed designs in the windows. Thus you can, for example, hide failed designs due to singularities or more closely analyze the causes of design problems.
The reinforcements and design ratios can be used as filter criteria in the RFEM work window, which can be accessed with the [Graphics] button. For this, the panel must be displayed. Should it not be active, it can be displayed by selecting
- View → Control Panel
in the RFEM menu or using the corresponding toolbar button.
The panel is described in chapter 3.4.6 of the RFEM manual. You can set the filter settings for the results in the first panel tab (color spectrum).
As shown in the figure above, you can set the panel's value scale in such a way that only reinforcements larger than 1.00 cm2/m are displayed. The color scale is set in such a way that a color range covers 1.00 cm2/m and the maximum value of 8.00 cm2/m suppresses effects of singularities.
The following chapter 6.4 explains how you can adjust the color and value spectra to the diameters and spacings of the rebars.
To display the grid point or FE node values in the graphics, the usual control functions of RFEM are available. They are described in chapter 9.4 of the RFEM manual.
In the Filter tab of the control panel, you can specify the numbers of selected surfaces to display their filtered results. This function is described in chapter 9.9.3 of the RFEM manual.
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 reinforcements.
