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.
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.
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.
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.
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 "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.
