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.
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.
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 "Stub" component is available to you in the Steel Joints add-on. It allows you to extend a member using a purlin joint with another member (stub) and to connect it to a reference component.
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 Concrete Design add-on for RFEM 6, you can perform the fire design of reinforced concrete slabs and walls according to the simplified table method (EN 1992‑1‑2, Section 5.4.2 and Tables 5.8 and 5.9).
In the Geotechnical Analysis add-on, the Hoek-Brown material model is available. The model shows linear-elastic ideal-plastic material behavior. Its nonlinear strength criterion is the most common failure criterion for stone and rocks.
You can enter the material parameters using
Rock parameters directly, or alternatively via
GSI classification.

In the Steel Joint add-on, you can define several ribs at the same time on one member or plate. The distribution can be carried out according to an orthogonal and a polar pattern.
You can use the "Plate Cut" component to cut plates (for example, gusset plates, fin plates, and so on). Various cutting methods are available:
Plane: The cut is performed on the closest surface to the reference plate.
Surface: Only the intersecting parts of plates are cut.
Bounding Box: The outermost dimension consisting of width and height is cut out of the plate as a rectangle.
Convex Hull: The outer hull of the cross-section is used for the plate cut. If there are fillets at the corner nodes of the cross-section, the cut is adapted to them.
The program does a lot of work for you. For example, the load or result combinations required for the serviceability limit state are generated and calculated in RFEM/RSTAB. You can select these design situations for the deflection analysis in the Aluminum Design add-on. Depending on the specified precamber and reference system, the program determines the deformation values at each location of a member. They are then compared to the limit values.
You can specify the deformation limit value individually for each structural component in Serviceability Configuration. In this case, you define the maximum deformation depending on the reference length as the allowable limit value. By defining design supports, you can segment the components. In this way, you can determine the corresponding reference length automatically for each design direction.
And that's not all. Based on the position of the assigned design supports, the program allows you to automatically determine the distinction between beams and cantilevers. The limit value is thus determined accordingly.
You can find the serviceability limit state design checks in the result tables of the Aluminum Design add-on. They are already fully integrated there. You have the option to display the design results with all the details at each location of the designed members. You can also use graphics with the result diagrams of the design ratios.
You can integrate all result tables and graphics into the global printout report of RFEM/RSTAB as a part of the aluminum design results. RFEM/RSTAB also allows you to display and document the deformations of the entire structure independently of the add-on.
For each load case, the deformations can be displayed at the end time.
These results are also documented for you in the printout report of RFEM and RSTAB. You can select the report contents and extent specifically for the individual design checks.
