Structural Engineering Software for Steel Structures
Structural FEM Analysis and Design
The successful structural analysis program RFEM 6 by Dlubal Software is the basis of a modular program family that you can customize and combine according to your precise requirements.
In the main program RFEM, you can define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. Furthermore, you can create combined structures as well as model solid and contact elements. Join our excited customers!
Structural Frame & Truss Analysis Software
Use our spatial frame & truss analysis software RSTAB 9 if you need a special solution tailored to beam, frame, and truss structures. Due to the special attention to such structures, it is even easier to use than the FEA software RFEM. RSTAB 9 has been the best choice for structural analysis and design of pure structural member models for many years.
Wind Simulation & Wind Load Generation
Do your structures have to withstand every gust of wind? Then it is best to use our stand-alone program RWIND 2. It is particularly recommended for complex model shapes. There are wind flows around all structures simulated in a digital wind tunnel.
You can easily import your generated wind loads acting on these objects into RFEM or RSTAB. Thus, you can complete your project there.
Stress Analysis of Member and Surface Structures
Use the Stress-Strain Analysis add-on for RFEM 6 / RSTAB 9 in your work. It performs general stress analysis by calculating the existing stresses and comparing the results with limit stresses.
Design of Members According to Various Standards
Select the Steel Design add-on for RFEM 6 / RSTAB 9 to keep your members stable and safe. The add-on designs steel members for the ultimate and serviceability limit state according to the standards:
- EN 1993-1-1:2005 + AC:2009 (Eurocode 3)
- AISC 360-16 (US standard)
- CSA S16-19 (Canadian standard)
- IS 800 | 2007-12 (Indian standard)
- GB 50017 | 2017-12 (Chinese standard)
- SP 16.13330 | 2017-02 (Russian standard)
Design of Steel Connections According to Finite Element Method
The Steel Joints add-on for RFEM 6 allows you to easily and efficiently analyze steel connections using an FE model.
Warping Torsion Second-Order Analysis with 7 Degrees of Freedom
The Torsional Warping (7 DOF) add-on for RFEM 6 / RSTAB 9 allows you to consider the cross-section warping as an additional degree of freedom when calculating members in RFEM and RSTAB.
Stability Analysis According to Eigenvalue and Incremental Method
To ensure the stability of your structures, opt for the Structure Stability add-on for RFEM 6 / RSTAB 9. It allows you to calculate critical load factors and the corresponding stability modes according to the eigenvalue method and the incremental method. Therefore, it is the perfect program for linear and nonlinear analysis of structural stability behavior.
Generation, Analysis, and Evaluation of Building Models
The Building Model add-on for RFEM 6 allows you to define and manipulate your building by means of stories. A big advantage is that you can adjust the stories in many ways afterwards. Information about the stories and the entire model (a center of gravity) is displayed in tables and graphics.
Consideration of Construction Stages
Stay on track of the construction process with the Construction Stages Analysis (CSA) add-on for RFEM 6. In RFEM, this allows you to consider the construction process of structures (member, surface, and solid structures). Do not concede any mistakes in your calculation of entire models! These may easily arise if the construction process is neglected. With this helpful add-on, you can analyze the influences and consider them right up to the structural design.
Model Optimization Using Artificial Intelligence (AI)
The two-part add-on Optimization & Costs / CO2 Emissions Estimation for RFEM 6 / RSTAB 9 is your reliable partner for model optimization. On the one hand, it gives you the suitable parameters for parameterized models and blocks via the artificial intelligence technology (AI) of the particle swarm optimization (PSO) in order to comply with the usual optimization criteria. On the other hand, it estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for your structural model.
Structural Dynamic Analysis
To keep your buildings safe even under stormy conditions, the Dynamic Analysis add-ons for RFEM 6 / RSTAB 9 are here for you. Use them to perform seismic design, vibration analysis of buildings, machine foundation design, natural frequency analysis for bridges and chimneys, and many other dynamic calculations.
Section Properties of Any Cross-Section
Keep an eye on your cross-sections with the RSECTION 1 program and benefit from the respective extensions. RSECTION 1 enables you to determine the cross-section properties, analyze stresses, and perform plastic design checks of any cross-section.
Add the Effective Sections extension of RSECTION to gain a simple and efficient solution for determining cross-sections according to EN 1993‑1‑5 and EN 1993‑1‑3. Your cross-sections and calculated section properties can be easily exported to the programs RFEM and RSTAB.
Structures with Cold-Formed Cross-Sections
For cold-formed cross-sections, the extension RF‑/STEEL Cold-Formed Sections for RFEM 5 / RSTAB 8 and the cross-section properties software SHAPE‑THIN (as of Version 9 and higher) are the best solution. Use these programs to design general cold-formed sections according to EN 1993&8209;1‑3 and EN 1993‑1‑5.
Plastic Design of Steel Cross-Sections
RF-/STEEL Plasticity is an extension that allows you to adapt the RF‑STEEL EC3 add-on module for RFEM& 5 / RSTAB 8 even more precisely to your project. Using this extension, you can perform the plastic design of cross-sections according to the partial internal forces method (TSV) and simplex method.
Generation of Imperfections
Use the RF‑IMP/RSIMP add-on module for RFEM 5 / RSTAB 8 to generate equivalent geometric imperfections (equivalent loads) or a pre-deformed equivalent model.
Fatigue Design of Members
Use the RF‑/STEEL Fatigue Members add-on module for RFEM 5 / RSTAB 8 to perform fatigue design of steel members or set of members according to EN 1993‑1‑9.
Design of Steel Connections According to Analytical Method
For the design of steel and timber connections, RFEM 5 / RSTAB 8 provides you with further powerful add-on modules.
Design of Crane Runway Girders
The CRANEWAY stand-alone program allows you to calculate and perform all required design checks of crane runway girders according to Eurocode 3. You can optionally select between bridge or suspension cranes.
Plate Buckling Analysis and Design for Plates with or Without Stiffeners
Use the PLATE‑BUCKLING stand-alone program or the RF‑/PLATE‑BUCKLING add-on module for RFEM 5 / RSTAB 8 to perform buckling safety design of rectangular plates according to the standard EN 1993‑1‑5.
Data Exchange Interfaces
The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. 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.
