Stress Analysis Software

Stress Analysis & Design of Member / Surface / Solid Structures

Structural FEA software RFEM and the frame analysis program RSTAB perform stress analysis of 2D and 3D structures.

In RSTAB, stress analysis is performed for member cross‑sections and in RFEM, also for surfaces and solids. In addition to normal and shear stress, you can also calculate contact stresses in RFEM.

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 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 frame and beam structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analyses.

Add-on Modules for RFEM and RSTAB

For design of various materials such as reinforced and prestressed concrete, steel, aluminium, timber, and glass, there is a wide range of powerful add‑modules available for the main program RFEM/RSTAB.

These modules allow you to perform nonlinear, stability and dynamic analyses as well as joint designs and form‑finding processes for cable and membrane structures.

Piping Stress Analysis

RF‑PIPING Design compares the existing pipe stresses with the allowable stresses according to EN 13480‑3, ASME B31.1, and ASME B31.3.

Design in RF‑PIPING Design is based on pipeline modeling in RF‑PIPING.

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.

Customer Projects of Stress Analysis

3D Steel Connection with RFEM Solid Elements, the Netherlands

For a project in Rotterdam, ADS Ertner used IDEA CONNECTION to analyze a structural steel connection. This program calculates steel connections utilizing the CBFEM method, where each thin-walled cross-section is modeled with nonlinear material properties, nonlinear bolts, and nonlinear welds.

New "Bharati" Indian Research Station in Antarctica

A new research station was built in East Antarctica for the Indian Ministry of Geosciences in the Antarctic summer months of 2010/11 and 2011/12. The design and planning come from the offices of bof Architekten and IMS Ingenieurgesellschaft in Hamburg, Germany.

The complex structure consists of an enveloping steel structure and a total of 134 special containers, which were integrated to transfer vertical and horizontal loads. The final structural analysis was carried out by the German engineering office of KSF in Bremerhaven.

Maze in Genk, Belgium

The temporary structure of a steel maze was created to celebrate the 10th anniversary of the C‑Mine arts center in Genk (Belgium), which is located at the former coal mine of Winterslag.
It took almost one month to install the steel structure at the arts center on an area of 15,069.5 ft².

Transportation of "Vechthoeve" House, Netherlands

At the end of 2013, the "Vechthoeve" was transported over a distance of 1,640 ft. The wooden house, referred to as the "Pippi Longstocking" house, is situated close to Amsterdam, the capital of the Netherlands. The villa had to be relocated because of plans to widen the A1 highway.

Segment gate with flap for the Niederfinow boat lift, Germany

The steel structure of a sluice with a flap gate is a part of the new Niederfinow boat lift on the east end of the Oder-Havel Canal in Germany.

It was built due to increasing traffic, as the original structure of the oldest working boat lift in Germany was running near capacity.

Industrial Filter Device, Germany

This project for designing a filter/dryer device, including agitator, required a complete stress and deformation analysis in RFEM.
The complex modeling of the structure, which had 1,424 surfaces, 158 solids, and 425 members, represented a special design challenge.
