The Müngsten Viaduct, completed in 1897, ranks among the most important buildings in steel bridge construction in the world today.
With a height of 351 ft over the Wupper River, it is Germany's highest railway bridge.
Many users rely on RFEM and RSTAB when analyzing and designing bridges consisting of steel, reinforced concrete, timber, or other materials.
By using the helpful add-on modules, it is possible to generate influence lines, moving loads on members and surfaces, and more. Dynamic analysis is also possible as well as required designs of stability, buckling, and fatigue.
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.
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.
Depending on the material used in bridge constructions, you can find more useful add-on modules for structural analysis and design under the Steel Structures, Concrete Structures and Timber Structures industries.
Other useful add-on modules:
A glass pedestrian bridge with a length of 30 m connects the St. Michael hospital with the research center Li Ka Shing Knowledge Institute.
The supporting structure consists of several oval steel rings which are twisted together.
The S‑shaped pedestrian and cycling bridge across the Neckar river in Germany, has a total length of 316 ft and a width of 10 ft.
Both foreland areas are bent in the ground plan and have a radius of approximately 214 ft.
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.
The "Walsersteg" bridge connects both sides of the Loisach river in the south of the old town of Wolfratshausen in Germany.
The pylon bridge for pedestrians and cyclists has a width of 3 m and a span width of 46 m.
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.
Janson Bridging in Hank, the Netherlands, produces temporary, emergency and permanent bridges for civil, industrial and military use.
All these bridges consist of modules with bridge spans ranging from 2 to 40 elements that can be joined using couplings.
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.
Moving loads can be easily generated with RF‑MOVE Surfaces. A library is available with load models as defined in the Eurocode 1, Part 2. The input of step size, offsets at start and end, and the distance to a reference line makes it possible for the user to generate user‑defined load models and also influence the number of generated load cases. RF‑MOVE Surfaces generates load cases and optional also a result combination as envelope of all results.
If you select the combinatorics according to EN 1990 + EN 1991‑2 and define a load case in the action category gr1a, gr2, or gr5, you have to additionally define in the program which load model should be taken as a basis for the load case. This information is crucial for defining combination rules for automatic combinatorics according to EN 1990 + EN 1991‑2. In the gr1a category, you can select TS (LM1), UDL (LM1) or pedestrian and cycle track, for example. TS (LM1) is preset by default. In the gr2 category, it is possible to select breaking and acceleration forces or centrifugal forces as a specification.
