Design and construction of the “Chaumény” footbridge in posttensioned UHPFRC
IABSE Reports, 2022 <p>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.
