AnswerIt is not allowed to transfer printout reports from one program to another. However, it is possible to include the SHAPE-THIN cross-section values and the SHAPE-THIN Cross tab with the RFEM or RSTAB printout report.To do this, open the printout report selection and add the cross-section details of the SHAPE-THIN cross-section, as described in Figure 1.
In principle, our software runs on a Microsoft Surface Tablet. Make sure that the tablet is equipped with the 64-bit version of Windows 10. The latest versions of RSTAB and RFEM are only available for 64-bit Windows.
However, one problem is that these tablets are all equipped only with an Intel graphics chip. The OpenGL implementation in its graphics driver is not very good. This may lead to crashes. A problem of the current graphics driver is that the nodes are not displayed in RSTAB and RFEM.
AnswerYou can perform the preliminary dimensioning of stiffening systems with our module SHAPE-THIN. Thus, the individual wall sections can be modeled and calculated with the theory of stiffening systems. The result is information about the centroid, shear center, and details about the cross-section values of the individual sections. Furthermore, it is possible to determine the individual shear forces in the walls. You can find further information in the links provided under this FAQ.
AnswerFigure 1 shows a bending-resistant carrier connection by fillet welds. The carrier profile is an IPE 300, S235. Outboard flange fillet welds (a = 7 mm, l = 150 mm), along the inside of the flanges fillet welds (a = 5 mm, l = 50 mm) as well as web double fillet welds (a = 4.5 mm, l = 239 mm) are used. The connection bending moment is M y = -106.11 kNm.
It is believed that the fillet welds are concentrated in the root lines.
A = 2 ∙ 0.7 ∙ 15 + 2 ∙ 0.45 ∙ 23.9 + 4 ∙ 0.5 ∙ 5.0 = 52.51 cm ²
I y = 2 ∙ 0.7 ∙ 15 ∙ 15.0² + 2 ∙ 0.45 ∙ 23.9³ / 12 + 4 ∙ 0.5 ∙ 5.0 ∙ (15 - 1.07) ² = 7690 cm 4
At the end of the web double fillet the following tension results:
σ ⊥ = 10611/7690 ∙ 11.95 = 16.49 kN / cm²The fillet welds are modeled in DUENQ and entered as the cut size M y = -106.11 kNm. The same values are obtained after the calculation as in the above calculation (see Figure 2).
All download links on our server are ok. However, the installations are very large files. They are significantly larger than 1 GB.
There may be a limit on download size in your network, or there may be a problem with your Internet connection.
Please contact your administrator for this. If the problem can not be solved, then there is also the possibility to send you the current version on a USB stick by post. In this case, contact the support via e-mail ( firstname.lastname@example.org ).
This is a false alarm. Our installation files are definitely free from viruses and other malware. This is carefully checked before each release of a new customer version.
The files are transmitted via a secure https connection, so that manipulation during transmission is also excluded.

With one click you can not install the Dlubal products. But there are tools to make the installation much more efficient.
Download the batch installer.
Place this program in any folder and save the Dlubal installation packages in the same folder or subfolders.
Start the installer.exe with a double-click. You will then be asked which products you would like to install and you can install them one after the other without the need of further mouse clicks.
AnswerIrregularities in the cross-sectional geometry can be mapped with point elements. They can be supplemented as a fillet, rectangle, circle or triangle or also removed from element surfaces. In this way, the area of the point element for the cross-sectional values can additionally be taken into account or excluded.Point elements can be inserted via menu Insert -> Cross section data -> 1 5 point elements or via the corresponding button in the toolbar (see Figure 1).No voltages are output at point elements.Point elements are not included in the calculation of the torsional moment of inertia. This can be compensated in the dialog Calculation parameters via a correction coefficient, to B. to detect pronounced fillets.Furthermore, corners and edges of the cross-section can be provided with radii of curvature and bends with the function "round off or bend corner". This function is called via menu Edit -> Round off or bend the corner (see picture 2). In the Corner Type section, specify whether the corner should be rounded or angled. Depending on the specification, in the Parameters section, the radius of curvature r or the shortening by the lengths l1 and l2 must be specified.The two elements are then - without closing the dialog - in the working window by mouse clickselect. In the section "Generating between elements no." become the numbers of the elementsdisplayed.If the checkbox Disconnect elements is active, after creating the arc or thenew element deletes the supernatants of the original elements in the corner area. The optionDelete Corner also removes the node in the corner.In addition, Corner Cornering lets you model corner areas in detail, without using rectangular point elements (see Figure 3). The function is called via the menu Edit -> Smooth the corner. Then click on one of the two elements in the overlap area in the working window. The relevant element side is shortened, the adjacent element side extended accordingly. A null element establishes the connection between the elements.
AnswerWhen importing tables, select File -> Import, activate the "Formulas in tables and parameters" check box in the "Options" tab of the "Import from Microsoft Excel - Settings" window (see Figure 1).When importing tables using the Excel button of the current table, activate the "Formulas in table" check box. If the parameters have not yet been created, select the "Parameters" check box (see Figure 2).
AnswerPoint elements represent relatively small objects in order to represent irregularities in the cross-section geometry. They can be added as a fillet, rectangle, circle, or triangle or removed from member surfaces. In this way, you can additionally consider or exclude the area of the point element for the cross-section properties. Point elements do not have stress points, so no stresses are determined on scaling points. Therefore, the point elements are irrelevant for the evaluation in the add-on modules and are not displayed graphically. Nevertheless, the point elements are considered in the cross-section values.
