In the Geotechnical Analysis add-on, the member of the type 'Pile' is available. Pile resistance types are created for the pile. It defines the parameters for the resistance from skin friction and the pile end pressure.
The pile is then embedded in the adjacent soil solid under consideration of the resistance characteristics 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.
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.
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.
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.
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 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.
The "Base Plate" component allows you to design base plate connections with cast-in anchors. In this case, plates, welds, anchorages, and steel-concrete interaction are analyzed.
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 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.

Using the "Rib" component, you can define any number of longitudinal ribs on a member plate. By defining a reference object, you can automatically specify welds on it.
The "Rib" component can also be arranged on circular hollow sections. This requires an additional definition of the angle between the ribs.
Global 3D calculation of the global model, where the slabs are modeled as a rigid plane (diaphragm) or as a bending plate
Local 2D calculation of the individual floors
After the calculation, the results of the columns and walls from the 3D calculation and the results of the slabs from the 2D calculation are combined in a single model. This means that there is no need to switch between the 3D model and the individual 2D models of the slabs. The user only works with one model, saves valuable time, and avoids possible errors in the manual data exchange between the 3D model and the individual 2D ceiling models.
The vertical surfaces in the model can be divided into shear walls and opening lintels. The program automatically generates internal result members from these wall objects, so they can be designed as members according to any standard in the Concrete Design add-on.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.
Shear walls and deep beams of a building model are available as independent objects in the design add-ons. This allows for faster filtering of the objects in results, as well as better documentation in the printout report.
You can now insert a cap plate in Steel Joints with just a few clicks. You can enter the data using the known definition types "Offsets" or "Dimensions and Position". By specifying a reference member and the cutting plane, it is also possible to omit the Member Cut component.
This component allows you to easily model cap plates on column ends, for example.
The building story generator in the Building Model add-on provides you with the option to automatically create building stories, depending on the topology of the model.
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.
Plates and structural elements can be precisely cut using the "Auxiliary Solid" component in the Steel Joint add-on. Within this component, you can use the shapes of a box, a cylinder, or any cross-section as a guide object.
The Timber Design add-on for RFEM 6 / RSTAB 9 is multi-purpose and combines a large number of additional elements. [*S16332764*]
Timber Design Add-on for RFEM 6
In the Steel Joints add-on, you can connect circular hollow sections using welds.
It is possible to connect the circular sections to each other or to planar structural components. The fillets of standard and thin-walled sections can also be connected with a weld.
