Design Software for Structural Steel Connections
FEM Analysis and Design of Structures
The structural analysis program RFEM is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
Analysis and Design of Beam Structures
The structural beam analysis program RSTAB determines internal forces, deformations and support reactions. For designs, there are various add-on modules considering the material and standard-specific circumstances. Due to the modular software system, it is possible to use the program package that perfectly meets your individual needs.
Design of Joints
Here you can find numerous add-on modules for the design of joints in steel and timber structures.
Interfaces for Data Exchange
The structural analysis software provided by Dlubal can be seamlessly integrated into the Building Information Modeling (BIM) process. A variety of interfaces allows you to exchange data from digital building models with RFEM or RSTAB.

Member Hinge Nonlinearity "Scaffolding Diagram"
The member hinge nonlinearities "Scaffolding - N phiy / phiz" and "Scaffolding Diagram" enable the mechanical simulation of a tube joint with an inner stub between two member elements.
The equivalent model transfers the bending moment via the overpressed outer pipe and after positive locking additionally via the inner stub, depending on the compression state at the member end.
- Which result combinations can I design with the RF‑/JOINTS Pro program and what should I pay attention to?
- How can I display the contact stresses on a contact solid?
- When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears saying that the value is out of the valid range (existing value: 108, minimum value 100, maximum value 100). What does this message mean?
- How do I create a frame joint with taper in JOINTS Steel - Rigid?
- How can I model and design general bolted connections with the surface and solid elements in RFEM?
- For design in FRAME‑JOINT Pro, I get Error No. 30011 "The selected nodes have different geometry [...]". How can I design my connection?
- I would like to calculate and design "temporary structures." What do I need for this?
- How can I perform the design of the tension resistance of a smooth column in a smooth bucket column base, that is, the design against pulling out the column?
- When modeling a beam connection to a continuous column, I have the problem that the column flange fails under bending. If I add backing plates in the FRAME‑JOINT Pro add-on module, nothing changes for all design ratios. Why?
- Is it possible to use one of the RFEM/RSTAB add-on modules to design a frame joint with a docked beam, stiffeners, and any number of bolt rows?
