Structural Analysis & Design Software for Cable and Tensile Structures
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.
The 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 engineers.
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.
The RF-FORM-FINDING add-on module for RFEM searches for shapes of cable and tensile structures. The shape is calculated by the equilibrium between the cable forces and the given boundary requirements. The prestressed model is afterwards used as the initial state for all subsequent calculations.
For structural analysis and design of cable and tensile membrane structures or their substructures, find more useful add‑on modules under the Steel Structures as well as Aluminium and Light-Weight Structures industry. If you would like to perform dynamic analyses, use the add-on modules for dynamic and seismic analysis.
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.
For twenty years, the Circus Festival in Latina has been thrilling audiences with the world’s most talented artists. The International Circus Festival of Italy, founded by Giulio Montico and operated by the Montico family, has been recognized globally since the first performance. The circus tent built in Latina has made it possible to appreciate the quality of the many artists performing there.
Removable guyed masts are used not only for telecommunications purposes, but also for collecting wind data in order to evaluate the profitability of a planned wind farm.
A unique project called "Oxigeno" is currently under construction in San Francisco de Heredia, San José, Costa Rica. The recreational and commercial space, which measures almost 1,345,489 ft², offers the visitor a relaxing shopping atmosphere in harmony with nature.
The signature feature of the Kauffman Center for the Performing Arts in Kansas City is the glazed atrium that connects the main entry to both performance venues. The glass facade and the glass skylight are supported entirely by the cable structure. The design was conceived as a cello’s strings.
A unique structure which roofs the main bus station in the Swiss town of Aarau was built at the end of 2013.
The canopy has a cloud-like shape and contains the largest single-chamber cushion in the world. It has a volume of 1810 m 3 and a roofed area of 1070 m 2 .
Since 2013, a new S‑shaped pylon bridge meanders across the Agger river near Lohmar, a town in West Germany.
Due to its curving shape, the bridge reflecting the course of the river is perfectly integrated into the landscape.
A very special project was carried out in Pitigala, Sri Lanka in 2013. A suspension bridge was designed, calculated and built by 30 students of the university team "Engineers Without Borders".
The 30-meter-long bridge across the Bentara river with was constructed with pure man power.
In October 2011, the sailing ship "Alexander von Humboldt II" started its service and has been conquering the seas ever since.
The ship operated by German Sail Training Foundation (DSST) is a barque rigged with three masts. The masts and the hull consist of steel.
Skywalk allgäu is a path leading through the treetops of the Allgäu Alps in Southern Germany.
The steel and timber structure of the path about 1,000 m above sea level consists of cable-stayed and suspension bridge constructions.

Activating the "Show Preliminary Form-Finding" option in the shortcut menu leads to an automatic preliminary form-finding according to the saved form-finding properties when you change the structure of membrane surfaces. This interactive graphics mode is based on the force density method.
