In addition to our technical support (e.g. via chat), you’ll find resources on our website that may help you with your design using Dlubal Software.
Frequently Asked Questions (FAQ)
Customer Support 24/7
AnswerFirst, it should be checked in which direction the self-weight of the structural elements acts. You can also display the self-weight graphically by using the "Display navigator" (see Figure 01). It often happens that the user does not convert the data when switching the global Z-axis, in the calculation parameters, and then only adjusts the geometry. The dead load acts in the wrong direction and must be signed correctly in the load case (see Figure 02).
AnswerThe RF-CONCRETE Columns add-on module uses the model column method with the nominal curvature or the nominal curvature method according to EN 1992-1-1.You can also find more information about the features of RF-CONCRETE Columns on the product homepage by using the following link. See links below.
AnswerIn the add-on module, the shear design is performed in the following sequence:1. VEd / VRd, c
2nd VEd / VRd, max
3. VEd / VRd, pIn the course of VEd / VRd, max, the inclination of the compression strut is determined and in the course of VEd / VRd, s, the reinforcement amount is determined iteratively.If VEd / VRd, max is not fulfilled in the design run, the subsequent design VEd / VRd, s is not performed and the design criterion VEd / VRd, c is displayed.
AnswerIn contrast to the normal surface or nodal load, a free load is defined by an influence range and influenced elements. By definition, the free loading is applied only to the areas of the selected elements lying within this influence range.A free load is defined via absolute coordinates, independent of the elements of the model. For entering data, you can define them comfortably by selecting Model nodes, but they will not be linked to the selected nodes. If the model is then moved, for example, the free load remains in its assigned position.If an imperfection generated by RF-IMP is used as a pre-deformed FE mesh, the free loads are applied to this deformed structure. This may then be beyond the influence range and receives no load.If the load is to be linked to the structure and also be moved for displacements and generated imperfections, standard loads must be used. Alternatively, it is also possible to increase the influence range of the free load as required to still stress the entire structure.A simple check of the applied loading is possible by displaying the load distribution in the Project Navigator - Results dialog box.
AnswerMake sure that no planned installation is currently performed. In Task Manager, this can be displayed as an active app and as a background process with the name "Windows Installer."If a Windows Installer is still displayed in the Task Manager after restarting the computer, it can be selected and closed by clicking the "End Task" button.Then, the desired installation can be carried out.
AnswerFree loads (such as free concentrated loads, free line loads, etc.) can not be transferred with the IFC interface.
AnswerFor lines, such an option is already directly accessible in the shortcut menu. For extruding the nodes into members and lines in surfaces, it is also possible in the detail settings of Copy / Rotate / Mirror. As soon as at least one copy is created, the new elements are also created.If you no longer need this feature, deactivate it again in the detail settings.
The files created with SHAPE-THIN 8 can not be opened in older program versions such as SHAPE-THIN 7. In SHAPE-THIN 8, you can not save files in a file format that older versions such as SHAPE-THIN 7 can read.However, the input data can be exported to Excel in SHAPE-THIN 8 (Figure 1) and imported into SHAPE-THIN 7 after adjusting the column arrangement.
AnswerYou can open profiles in SHAPE-THIN 8 that have been created with the following program versions:
- SHAPE-THIN 5.xx,
- SHAPE-THIN 6.xx,
- SHAPE-THIN 7.xx,
- SHAPE-THIN 7.5x and
- SHAPE-THIN 8.xx
Profiles from the DOS versions SHAPE-THIN 1.xx and SHAPE-THIN 2.xx can not be imported in SHAPE-THIN 8.
If the section was defined on an unused line, activate the "Integrate unutilized objects into surfaces" check box in the FE mesh settings. In Figure 1, a section on lines 7 and 12 is defined. Line 7 has no other function for surface 1. It is neither the boundary line of surface 1, nor does it have a support or a load. In the FE mesh settings, the "Integrate unused objects into surfaces" check box is clear so that no result diagrams are displayed on line 7. In contrast, line 12 is stressed so that result diagrams are displayed on this line. If the "Integrate unused objects into surfaces" check box is selected, result diagrams are also displayed on line 7.
If the section runs through several surfaces, the respective surfaces are listed in the "On Surface No." section specify. Figure 2 shows a section through Surfaces 3 and 4. In the "On Surfaces No." section only the surface 3 is specified so that result diagrams are only displayed on this surface. Surface 4 would be described in the section "On Surfaces No." so that result diagrams are also displayed here.
