Rolled sections, the most common cross‑section type in RFEM and RSTAB, can also have user‑defined parameters. To do this, select the cross‑section to be modified in the cross‑section library and click the [Parametric Input...] button.
If you want to consider guide objects in the overall view (F8 key or double-click on the mouse wheel) or, for example, in a particular direction of the views, you can enable this option in the settings of the particular guide objects (guidelines, background layers, line grids).
In RFEM and RSTAB, you can check the plausibility of entries before you start the calculation. This is done using "Tools" → "Check Plausibility ..." or the corresponding button in the toolbar. There are three different types of checks available.
In RF‑TENDON and RF‑TENDON Design, you can review and adjust the code‑dependent factors, calculation parameters, and calculation methods using the "Code" button. You can display the settings and adjustment options according to a chapter of a code, selecting the "Grouping" option in the dialog box.
The RF‑/JOINTS add‑on modules are equipped with a graphical window that shows all the structural components of the connection. There, you can use the mouse functions known from RFEM and RSTAB to zoom, move, or rotate the view.
For a quick overview of the cross‑sections used, you can show the members in color sorted by cross‑section. Use the right mouse button in the work window to select "Colors in Graphics According to" → "Cross -Sections" from the shortcut menu. In the current program versions, you can use a panel with an editable color scale for this.
It is necessary to design some structures in different configurations. It may be that an aerial work platform must be analyzed in its position on the ground as well as in the middle and in the extended position. Since such tasks require the creation of several models, which are almost identical, updating all the models with just one mouse click is a considerable relief.
After running an analysis in RF-/STEEL AISC, the mode shapes for sets of members can be viewed graphically in a separate window. Select the relevant set of members in the result window and click the [Mode Shapes] button.
In order to use internal forces from average regions also for the design of concrete surfaces, you have to activate them in the module. For this, click the [Details] button in the "Tools" tab and select the option "Apply the averaged internal forces in the defined average region for the ULS calculation and for the analytic method of SLS calculation."
Member properties can be imported from the previously defined member in the "New Members" and "Edit Member" dialog boxes. To do this, click the [Select member and import its properties to the dialog box] button, then select the respective member.
Sometimes, a model in the graphic window is displayed without filling the entire window, or with overly large margins after clicking the [Show Whole Model] button. To set the size of the graphic margins, click "Options" → "Display Margins and Stretch Factors". The value specifies the percentage of the margin relative to the graphic window size.
Click the [Details] button in RF-GLASS to select the results to be displayed. In order to get a better overview for the result evaluation, you can select the individual stress graphics (principal stresses, stresses oriented to axes, shear stresses) as well as various result windows. This way, you can show only the results you require.
As in RFEM, load combinations can be generated automatically in RF‑PIPING. This feature is activated by default and creates the recommended load and result combinations for piping design. It is necessary to assign the relevant action category to load cases in order to generate the correct combinations. To do this, new action categories have been implemented specifically for loads on piping. Pressure temperature conditions are generated as the sets of the first (second, third, and so on) load case of the "Pressure" category and the first (second, third, and so on) load case of the "Temperature" category. The default setting can be reviewed or adjusted in the "Grouping of Thermal and Internal Pressure Load Cases for Operating Combinations" dialog box. You can access this dialog box by clicking the corresponding button in the "Piping Load Combinations" tab of the "Load Cases and Combinations" dialog box. This dialog box is automatically offered to check your entries in the case of any change of the load case from the "Pressure" or "Temperature" category.
You can quickly add surfaces to grates or facade elements using the "Create Surfaces from Cells" function. This function can be found under "Tools" → "Generate Model – Surfaces" and it recognizes all the cells of the entire model. Click the "Select Cells" button to select the respective cells. In addition to the material and thickness, you can specify the stiffness of all surfaces to be created.
RFEM and RSTAB are programs where graphical input prevails. All data can be entered using dialog boxes, and the structure of the Project Navigator is optimized for input using the mouse. Nevertheless, you can always speed up the tabular input to reach your goal immediately.
RFEM and RSTAB provide the export interface ("File" → "Export") to export model and load data, as well as results, to Excel or in a CSV file in one step. You can select the tables to be exported in the "Export Tables" section. The "Only selected tables" option allows you to export only a specific selection of tables. Use the [Select Load Cases and Tables for Export] button to open the corresponding dialog box.
Using the [To Display…] button, you can specify the amount of reinforcement to be displayed in the results of the required reinforcement in Window 2.2 of RF‑CONCRETE and CONCRETE. In addition to the default setting, you can display the resulting reinforcement amount as (for example) the sum of the longitudinal and longitudinal torsion reinforcement, or the sum of the torsion and shear reinforcement. You can also reduce the number of preset results, of course.
The result window of the cross-section properties can be adjusted individually using the [Filter] button in the table menu bar. You can then activate or deactivate the individual cross-section parameters in the dialog box.
The "Info About Member" feature is available in RFEM and RSTAB. allows you to quickly read the member properties and results in a graphic. When you move the mouse over a member, the information about the member is displayed in the corresponding window.
With the introduction of OSG graphics for the representation of design reinforcement in RF‑CONCRETE Members and CONCRETE, you can also select the reinforcement position directly in the graphic. Right-click the mouse to open the context menu where you can edit, copy, or delete the selected reinforcement position.
User-defined views are a very useful tool for effective modeling, as the previously selected and adapted objects appear directly with a click of the mouse. These objects can also be used easily to create informative and clearly arranged result graphics. With just a few clicks, you can create all result graphics at once using the mass print function.
