Design Software for Structural Steel Connections
Structural FEM Analysis and Design
The structural analysis software RFEM 6 is the basis of a modular program family. The RFEM main program 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.
Connection Design
Here you will find numerous add-ons for steel connections as well as add-on modules for the connection design in steel and timber structures.
Interfaces for Data Exchange
The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces ensures the data exchange of digital building models with RFEM or RSTAB.
The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.
Support and Learning
Customer service is a fundamental pillar of the Dlubal Software company philosophy. We provide any necessary support you need to complete your daily work.

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 "flying 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 design a restrained column base with stiffeners on both sides of the column in any of the RFEM/RSTAB add-on modules?
