Ötztaler Achbridge (case study)

The 'Ötztaler Achbrücke' railwaybridge is located on the Innsbruck - Bludenz route in Tirol, Austria and was completed in 2011. The three-field composite steel structure has a total length of 144.6 m, the spans of the individual fields are 42.0 m - 60.6 m - 42.0 m. The support structure consists of two abutments and two pillars, deeply founded. The longitudinally displaceable bearings are located on both abutments, while the pillars are rigidly connected to the bridge structure.

Object analysis

The time recording of the measurement data took place in the period from August 25, 2011 to June 30, 2013. On the basis of long-term measurements during this period, the stretching / displacement behavior of the rails in particular was described.
