Title:	Neubau Negrellisteg
Abstract:	Dieses Projekt wurde mit einem Prix Acier 2021 ausgezeichnet Im Frühling 2021 wurde der Negrellisteg über das Zürcher Gleisfeld eröffnet. Damit gingen intensive und anregende Planungs- und Bauphasen zu Ende. Dieser Bericht gibt Einblick in die technischen Aspekte der Konstruktion und des Bauvorgangs dieser 160 m langen Fußgängerbrücke. Dabei wird auf die besonderen Herausforderungen eines monolithischen Bauwerks, welches auf bestehenden Betonbauwerken fundiert wurde, eingegangen. Weiter wird die für stählerne Fußgängerbrücken besonders relevante Schwingungsthematik beleuchtet. Der Bauvorgang im innerstädtischen Umfeld über dem Gleisfeld des größten Schweizer Bahnhofs erforderte bei der Ausführung ebenfalls besonderes Augenmerk. Negrellisteg In Spring 2021 the Negrellisteg over the Zurich railway field was opened. With this, intensive and attractive planning- and building phases ended. This report gives an impression to technical aspects of the structure and the building period of this 160 m long pedestrian bridge. In particular, the challenges of a monolithic structure which is founded on existing concrete infrastructure are mentioned. Further, dynamic aspects which are very important for steel pedestrian bridges are discussed. Last but not least the construction process in the environment of the biggest Swiss railway station needed as well special attention.
