AnswerThe result display with result values on surfaces is very helpful for this.It is already preset that only extreme values are displayed. In addition, you can specify in the Results navigator whether the extreme values of the entire model, all surfaces or solids, or all local peak values should be displayed.
AnswerResult values can be rotated by an arbitrary angle (see Figure 1). With this setting, all result values are rotated. So far, you can not define different orientations for single walls and ceilings.
AnswerPlease note that in the context of the nonlinear calculation, the reinforcement is not increased automatically. A nonlinear calculation is based on an already provided reinforcement. This provided reinforcement can result, for example, from the ultimate limit state designs or a defined ground reinforcement. The reinforcement applied for the SLS designs can be displayed graphically (see Figure 2).Cause of issue:If no reinforcement results from the ULS or the basic reinforcement in some areas, the serviceability limit state design is carried out without the applied reinforcement, and very high results may result, for example in the crack width.Solution to the problem:It should be ensured that there is a reinforcement in each zone of the structure. This can be implemented by applying a basic reinforcement (see Figure 3).
AnswerThis is due to the fact that the respective corner nodes for defining the arealas plane are duplicated in the selection window. If one of them is deleted, the correct values are displayed in the info window after clicking OK.
AnswerFor the pile tip resistance, the bedding must be multiplied by the cross-sectional area (see Figure 1).For skin friction, the bedding must be multiplied by the circumference of the cross section (see Figure 2).
Right-click one of the values and select 'Display Properties' in the shortcut menu to get directly to the required setting: Here you can make settings in both tabs 'Screen' and 'Printout Report', for example to set transparent or coloured display of the values or the background colour of the values.
I have modified cross-section properties or reduced stiffnesses of a members in RFEM/RSTAB. After a new calculation, the deformation of the structural system has adjusted itself to the new cross-section properties. However, this change is not taken into account when performing design in add-on modules.
In principle, the modified cross-section properties are not transferred into add-on modules, such as RF‑/STEEL or RF‑/STEEL EC3. They are only used for the calculation of internal forces.
In the add-on modules, stresses are calculated using the real cross-section dimensions, which cannot be modified. This would be difficult to implement as many designs require the element width or height and due to the modification, it is not known which parameter has been reduced exactly. This is important for the c/t-designs in RF‑/STEEL EC3, for example.
If the corresponding check box is selected in the Display navigator, all intermediate values for the local member deformations are displayed. The same applies to the result diagrams (see Figure 01).
Depending on how many intermediate nodes are defined for the respective member, the result tables do not only show nodal values and the maximum values, but also the corresponding deformation values in the division points (see Figure 02).
In most cases, the problem is solved by right-clicking one of the displayed grid results and selecting the "Show All" option in the shortcut menu (see Figure 01).
The results should now be displayed on each grid point, both in the results graphic and in the printout report.
So that the result values of the bearing forces are not displayed one above the other, you can adjust the "display factor" for the bearing forces in the result panel (to the right of the graphics window).
If you enlarge it, the presentation should be better (see Figure 1).
Alternatively, you can also right-click in the graphics window and adjust the "Display Properties". Under the category "Results"> "Storage reactions"> "Nodal forces" you can adjust the size of the representation.
If the input has an effect, you can also adjust the "Relative limit settings" in the detail settings (see Figure 2).
If you only want to display a value "Max" or "Min value" in the EC results, you can set this in the result navigator for the EC results (see Figure 3).
