Freischütz Pedestrian Bridge, Germany
As part of the 4-lane widening of the federal highway 236 between Dortmund/Schwerte and the Schwerte motorway junction of the Autobahn 1 highway, the existing Freischütz pedestrian and cyclist bridge was renewed.

VIC Planen und Beraten GmbH
The Dlubal customer Verkehrs- und Ingenieurbau Consult GmbH (VIC) was responsible for the structural analysis and the execution planning of the bridge. For the structural analysis, the FEA software RFEM and the cross-section properties software SHAPE‑THIN were used.
Structure and Design
The Freischütz pedestrian and cyclist bridge is basically a Vierendeel truss with a curved floor plan, which is the transom of an integral frame structure. VIC modeled in RFEM the main supporting structure of the steel bridge with members made of hollow box sections, and the foundations with concrete solid elements. The span of the bridge is approx. 111.5 ft. As traffic load, it was necessary to apply the pedestrian loads as well as the special vehicle loads.
In addition to the structural analysis according to RE‑ING 2‑5, Difficulty Class 3, the vibration behavior of the bridge was also analyzed. The dynamic analysis result proved that normal pedestrian traffic can only excite the structure to low levels of vibration, which do not affect its serviceability.

CSA S16:19 Stability Considerations and the New Annex O.2
The CSA S16:19 Stability Effects in Elastic Analysis method in Annex O.2 is an alternative option to the Simplified Stability Analysis Method in Clause 8.4.3. This article will describe the requirements of Annex O.2 and application in RFEM 6.
- How can I model a rib element in RFEM 6?
- The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
