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.

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.

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.

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.

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.

Main Program RFEM

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.

Frame Analysis Software RSTAB

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.
