Abstrait:

A landmark bridge in Odense is being prepared by NIRAS and ES-Consult based on an architectural concept of a curved bridge in steel and concrete including a 35 m high pylon. Being an advanced structural system the challenges have been to optimize the statics and minimize restraint forces of the slender bridge. The bridge is built over a railway terrain as two steel box girders, supported by a few steel columns which requires high focus on the erection phase. The remaining bridge is cast in-situ concrete and supported by concrete columns spaced relatively closely. Steel design and unique foundation design have been some of the challenges besides advanced finite element modelling. Dynamic investigations have been conducted and the lowest vertical eigenfrequency of 2.15Hz may prove to require installation of tuned mass dampers.
