Structural Analysis Software for Steel Structures

Structural Analysis & Design of Steel Structures

The structural analysis programs RFEM and RSTAB together with the corresponding steel add-on modules are the optimal solution for the structural analysis and design of steel structures such as steel buildings, steel halls, scaffoldings, bridges, silos, cranes, crane runways, masts, winter gardens, etc.

The modular software system of Dlubal consists of the main program RFEM (FEA) or RSTAB (member structures) and the corresponding add-on modules.

  • Steel structure
  • Bionic Steel Structure
  • Steel Frame Structure
    Many structural engineers use the structural analysis software RFEM (FEA) or RSTAB (frames and trusses) for the structural analysis of steel halls.

    By using the helpful add-on modules, it is possible to perform all required designs for ultimate limit state, stability and serviceability according to various standards. Dynamic calculations are possible as well as additional design checks for fire resistance or fatigue.

  • Terminal Building
  • Extension of Continuous Casting Plant
    RFEM and RSTAB are ideal for structural design and analysis of industrial constructions. These include chemical, pharmaceutical, petrochemical, industrial, metal, mineral process plants as well as production halls, containers, pipeline systems, large filters, and so on.

    RSTAB allows for design of member structures and RFEM for additional plate, wall, shell, and solid elements.

    Structural Analysis and Design of Industrial Plants

  • Spatial Steel Connection
    More complex 3D steel connections can be modeled and designed utilizing the FEM structural analysis software RFEM. The connection is modeled with surface and possibly solid elements.

    In order to consider the contact effects as well as the plastic material behavior, nonlinear geometric and physical properties are activated in RFEM.

    Structural Analysis and Design of Steel Connections

  • Facade Structure
    The structural analysis programs RFEM (FEA) and RSTAB (frames and trusses) as well as the stand-alone program SHAPE-THIN 9 perform the design of facade structures such as glass facades, curtain walls, double facades, element facades, etc.

    RWIND Simulation allows you to simulate wind flows around buildings or any other objects by means of a digital wind tunnel and to generate wind loads.

    Calculation of Facade Structures

  • Steel offshore structure
    The analysis and design of offshore structures such as drilling platforms, wind power plants, research platforms, and many others, applies many features of RFEM and RSTAB.

    These features include the analysis of structures consisting of several materials, dynamic analysis, stability analysis, fatigue designs, generation of loads due to rotation, wind simulation, and other functions.

    Offshore Structural Analysis Software

  • Steel Hall
  • Steel dome
  • Steel bridge
    Many users rely on structural analysis software RFEM (FEA) and RSTAB (frames and trusses) when analyzing and designing bridges consisting of steel.

    By using the helpful add-on modules, it is possible to generate influence lines, moving loads on members and surfaces, and more. Dynamic analyzes are also possible as well as required designs of stability, serviceability limit state, fatigue and buckling.

FEA Structural Analysis

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 & 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

The RWIND Simulation stand-alone program is recommended for complex structures. Utilize this program to simulate wind flow (digital wind tunnel) around buildings or any other objects and generating wind loads, i.e. forces acting on these objects based on CFD.

Import the generated wind loads acting on these objects to the structural analysis and design software RFEM or RSTAB.

Stress Analysis of Member and Surface Structures

The RF-/STEEL add-on module performs general stress analysis by calculating the existing stresses and comparing the results with limit stresses.

Design of Members According to Various Standards

The following add-on modules perform all typical ultimate limit state design, stability analyses, and deformation analyses for structural steel:

Structures with Cold-Formed Cross-Sections

With the RF-/STEEL Cold-Formed Sections module extension and the SHAPE-THIN cross-section program (version 9 and higher), you can design general cold-formed sections according to EN 1993-1-3 and EN 1993-1-5.

Warping Torsion Second-Order Analysis with 7 Degrees of Freedom

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

Plastic Design of Steel Cross-Sections

RF-/STEEL Plasticity is an extension of the RF‑/STEEL EC3 add-on module. This allows for the plastic design of cross-sections according to the partial internal forces method (TSV) and simplex method.

Stability Analysis According to Eigenvalue Calculation Method

The RF-STABILITY add-on module for RFEM and the RSBUCK add-on module for RSTAB calculate the buckling modes as well as the critical loads of the model based on the eigenvalue analysis. The add-on modules are therefore suitable for the linear and nonlinear analysis of the structural stability behavior.

Generation of Imperfections

The RF-IMP/RSIMP add-on module is used to generate equivalent geometric imperfections (equivalent loads) or a pre-deformed equivalent model.

Fatigue Design of Members

The RF-/STEEL Fatigue Members add-on module allows you to perform fatigue designs according to EN 1993‑1‑9 for steel members and sets of members.

Design of Crane Runway Girders

The CRANEWAY stand-alone program calculates and performs all required designs 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

The PLATE-BUCKLING stand-alone program or the RF‑/PLATE‑BUCKLING add-on module performs plate buckling analysis of rectangular plates according to the standard EN 1993‑1‑5.

Design of Thin-Walled Cross-Sections

The SHAPE-THIN stand-alone program determines section properties and performs stress analysis and plastic design of any thin-walled cross-sections. The cross-sections and the calculated section properties can be exported to the main programs RFEM or RSTAB.

Structural 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.

Steel Connection Design

RFEM and RSTAB provide powerful add-on modules for design of steel and timber connections.

Data Exchange Interfaces

Structural analysis programs by Dlubal Software integrate seamlessly into the Building Information Modeling (BIM) process. A large number of interfaces ensure the data exchange of digital building models with RFEM or RSTAB.
