| Abstract: |
In 2020/21, the “Chaumény” footbridge was built in posttensioned UHPFRC over a railway line in the city of Montreux, Switzerland. UHPFRC stands for Ultra High Performance Fiber Reinforced Cementitious composite. UHPFRC shows high resistance both in tension and compression as well as excellent durability properties. The design and construction of the lightweight structure is described. The structure consists of a U-shaped trough girder with a span of 22.5m above the railway clearance, resting on one abutment and one pier, as well as a staircase leading from the pier down to the ground. The footbridge is composed of several precast elements that were assembled by posttensioning to achieve monolithically linked structure. |
