The moving load wizard allows you to generate moving loads on surfaces. You can apply single loads or load models consisting of several loads to your structural system.
According to the entered parameters, such as moving step, start and end offset, the corresponding load cases are created automatically.
The moving load wizard is directly integrated in RFEM and does not have to be purchased separately.
In the Aluminum Design add-on, you can consider a localized strength reduction in the HAZ using transverse welds in the design according to EN 1999‑1‑1.
Furthermore, the Effective Sections add-on in RSECTION allows you to calculate the effective cross-section, taking into account the transverse weld according to EN 1999-1-1.
To transfer pure member structures (including loads, load cases, load combinations, and imperfections), you can use the DSTV product interface for steel structures in RFEM 6/RSTAB 9.
Die DSTV-Schnittstelle ermöglicht Ihnen den Datenaustausch zwischen RFEM 6 / RSTAB 9 und Programmen wie 'Bentley ProStructure 3D', 'Tekla Structures', 'Bocad', 'Intergraph Frameworks', 'Graitec Advance Steel', 'Cadwork' und vielen anderen.
In the Geotechnical Analysis add-on, the member of the "Pile" type is available. For the pile, the pile resistance types are created. They define the resistance parameters from the skin friction and the pile peak pressure.
The pile is then embedded in the adjacent soil solid, while considering the resistance properties resulting from the parameters of the skin friction and the peak pressure.
You can use the SDNF interface to import and export data such as materials, cross-sections, members, and surfaces in RFEM 6 and RSTAB 9. This allows for file-based data exchange with programs such as Tekla Structures or Advance Steel.
The DXF interface II is based on a different technology than the DXF interface. It provides additional features such as export of deformed mesh, export of dimension lines, etc.
With the new functions 'Unite Lines' and 'Unite Members', you can combine several lines/members into a single line or member without deleting the common nodes. There are several ways to access the functions:
In the Steel Joint add-on, you can use not only the usual member types of "Beam", "Truss", and so on, but also the member type of "Result Beam", as well as cross-sections from surface elements. You should select a suitable cross-section for the result beam and then define any member openings in the surface model using the member editor.
You have the option to exclude objects, such as members, surfaces, and so on, from the design by load combination (CO) / result combination (RC). You can specify the data in the "Objects to Exclude" tab of the table. Thus, you can design certain objects with certain load combinations only. This option is available in all design add-ons, except the "Steel Joints" add-on.
The design results of the add-ons can be optionally displayed in the tables by design situations. This allows you to evaluate the results in great detail.
In the combination wizard, you can create final result combinations using auxiliary combinations. In the case of models with many load cases (for example, moving loads for bridges), you can use this option to generate result combinations that are more transparent and thus easier to check.
The "Surface Contact" component in the Steel Joints add-on allows you to take into account a pressure contact between two parallel plates/member plates. Furthermore, you can optionally consider the friction between the surfaces.
The "Results by Story" table of a building model shows the center of gravity for load cases and load combinations. In addition to the self-weight, the vertical loads of the respective load cases and load combinations are also taken into account.
You can also use the "Center of Gravity and Information About Selected Objects" dialog box to display the center of gravity, taking into account the selected loading.
For the "Load Transfer" surface stiffness type, curved geometries are available, such as "Quadrangle", "NURBS", and "Rotation", in addition to the "Plane" and "Pipe" geometry types.
In the Geotechnical Analysis add-on, the high-quality material model "Modified Hardening Soil Model" is available. This material model is suitable for a variety of soils and is able to appropriately represent the following properties of the real soil.
Stress dependence of soil stiffness
Load path dependence of soil stiffness
Plastic strains even before reaching the limit condition
Increasing shear resistance with increasing mesh refinement
Increasing yield strength with increasing stress until reaching the limit yield condition
Failure criterion according to Mohr-Coulomb
You can find more information about this material model and the definition of the input in RFEM in the corresponding chapter of the online manual for the Geotechnical Analysis add-on.
In the Dlubal Center, there is an extensive library with connections available for the Steel Joints add-on.
You can access this library directly from the add-on and assign the predefined connections to the corresponding nodes. You can also save user-defined connections in the library in Dlubal Center.
The "Create surface cells due to openings" option is available to you in the surface shortcut menu. It allows you to easily create the lines for the columns of timber panel walls (using the "Beam Panel" thickness type), for example.
In the Steel Joint add-on, you can arrange plates in various geometry shapes. In addition to the "Rectangle" and "Circle" shapes, the "Polygon" shape is also available. The polygonal shape is defined by entering the point coordinates.
In the Import Support Reaction load wizard, the Free Loads object connection type is available in addition to the Manual types. This option saves you the task of manually assigning the support reactions to specific nodes and lines. The support forces of the connected model are applied as free loads in this version.
After the load transfer, you can decouple the loads from the load-bearing models at any time.
You can use the "Spline with minimum curvature" type of surface geometry to generate curved surfaces on the basis of control nodes in the middle of the surface.
You can use this option to model terrain surfaces, for example.
When modeling stories, you can use the "Semi-Rigid Diaphragm" option for slabs.
In principle, this modeling option selects the same approach as for the "Rigid Diaphragm" modeling of stories. In contrast to the rigid diaphragm, no nodal coupling is carried out from the center of gravity to each FE node. This way, it is possible to take into account the flexibility of the slab.
