Nonlinear Buckling Analysis
Do you already know the structural analysis program RFEM 6? As a basis of the modular program family, it is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells, and members. Do you want to use different elements in your project? No problem. RFEM also allows you to create combined structures as well as to model solid and contact elements.
The stability of structures is an important factor when planning your project. Dlubal Software has just the right add-on for this. No matter whether you work in RFEM 6 or RSTAB 9, because you get the Structure Stability add-on for RFEM 6 / RSTAB 9. This extension calculates critical load factors and the corresponding stability modes according to the eigenvalue method and the incremental method. Therefore, you can use it for both linear and nonlinear analysis of the structural stability behavior.
Things don't always run smoothly in life. You should also be prepared for all eventualities when planning your structural projects. RFEM 6 will help you. The Nonlinear Material Behavior add-on for RFEM 6 allows you to consider nonlinear material behavior in RFEM (for example, isotropic plastic, orthotropic plastic, isotropic damage). You can thus avoid any unpleasant surprises in the end.
Are you looking for more options for your structural analysis software? The RF‑IMP/RSIMP add-on module for RFEM 5 / RSTAB 8 helps you to generate equivalent geometric imperfections (equivalent loads) or a pre-deformed equivalent model. Thus, you get another helpful partner at your side.
At Dlubal Software, everyone works hand in hand. So do the structural analysis programs. The Dlubal structural analysis software can be seamlessly integrated into the Building Information Modeling (BIM) process to work together without any problems. The large number of interfaces allows you to exchange the data of digital building models with RFEM or RSTAB.
Use the Webservice (a programmable interface) to read or write the data from or to RFEM and RSTAB.

In the case of rectangular cross-sections, you can typically achieve a direct connection by means of welds. However, you can also connect them to other cross-sections in the same way. Furthermore, other components such as end plates help you to connect rectangular cross-sections to other components.
- How can I determine the controlling internal forces at a node that several members frame into for connection design?
- 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?
- How is the rotational stiffness of a buckling stiffener determined in PLATE‑BUCKLING?
- 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?
- For a buckling analysis, PLATE‑BUCKLING determines the governing shear stress of τ = 7.45 kN/cm², while RF‑/STEEL gives the result of the maximum shear stress of τ = 8.20 kN/cm². Where does this difference come from?
- 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?
