Steel Structural Analysis & Design Software

3D Finite Element Analysis and Design

Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells, members (beams), solids, and contact elements.

Analysis & Design of Frame/Beam/Truss Structures

Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to beam, frame, and truss structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analysis.

Wind Simulation & Wind Load Generation

Use the stand-alone program RWIND Simulation for complex structures. This program simulates wind flows around any structures by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

Stress Analysis and Design

RF-/STEEL performs general stress analysis of members and surfaces by calculating the existing stresses and comparing the results with limit stresses.

Steel Design According To Various Codes

The following add‑on modules perform all characteristic designs of the ultimate limit state and the serviceability limit state as well as deformation analyses for structural steel.

Cold-Formed Sections

Design general cold-formed sections according to EN 1993-1-3 and EN 1993-1-5 with the RF-/STEEL Cold-Formed Sections module extension and the SHAPE-THIN cross-section program (from version 9).

Warping Torsion Second-Order Analysis with 7 Degrees of Freedom

RF‑/STEEL Warping Torsion is an extension of the RF-/STEEL AISC and RF‑/STEEL EC3 add‑on module. It performs flexural-torsional and lateral‑torsional buckling analysis of members according to the second‑order theory with 7 degrees of freedom and application of imperfections with regard to mode shapes.

Plastic Design of Cross-Sections

RF-/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add‑on module. It allows for plastic design of cross‑sections according to Partial Internal Forces Method or Simplex Method.

Eigenvalue Stability Analysis

RF-STABILITY/RSBUCK determines buckling modes and critical load factors of the model using the Eigenvalue Method. Therefore, it is especially suitable for linear and nonlinear analysis of stability behavior.

Generation of Equivalent Geometric Imperfections and Pre-Deformed Initial Models

RF-IMP/RSIMP creates equivalent geometric imperfections (equivalent lateral loads) or a pre‑deformed initial model.

Fatigue Design

RF-/STEEL Fatigue Members performs fatigue design of members (beams) and sets of members in compliance with the standard EN 1993‑1‑9.

Design of Crane Runway Girders

CRANEWAY calculates and performs all required designs of craneway girders according to Eurocode 3. Optionally, you can select bridge or suspension crane.

Plate Buckling Analysis for Plates With or Without Stiffeners

Stand-alone software PLATE‑BUCKLING or add-on modules RF‑/PLATE‑BUCKLING perform plate buckling analysis of rectangular plates according to EN 1993‑1‑5.

Section Properties of Thin-Walled Cross-Sections

Stand-alone cross‑section analysis software SHAPE‑THIN determines cross-sectional properties, performs stress analysis and plastic design of any thin-walled cross-section. It is possible to export cross-section and calculated section properties to main programs RFEM or RSTAB.

Dynamic Analysis

Add-on modules for dynamic analyses are suited for seismic design, vibration analysis of buildings, machine foundation design, natural frequency analysis for bridges and chimneys, and many other dynamic calculations.

Structural Design of Steel Connections

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.
