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 "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.
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.
You can neglect openings with a certain area in the building model calculation. This function can be activated in the global settings of the building stories. A warning message appears saying that the openings have been neglected.
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.
The Modal Analysis add-on provides you with the option to automatically increase the sought eigenvalues until a defined effective modal mass factor is reached. All translational directions activated as masses for the modal analysis are taken into account.
Thus, it is possible to easily calculate the required 90% of the effective modal mass for the response spectrum method.
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).
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.
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.
