Abstract: 
Within the works for upgrading and extending the Olympic museum at Lausanne (Switzerland) a new roof has been built to cover the existing building (finished in 1990). The new roof acts also as an unusual canopy, shading natural light in the south part of the building. It is composed of a grid of beams cast in ultra-high performance fibre reinforced concrete (UHPFRC). A comparison to other options (timber and aluminium members) has proven the UHPFRC solution to be the most competitive accounting for all requirements of the structure (economy, durability, easiness of construction, architectural expression, weight and construction details). Long lengths of the beams (up to 21 meters) have been obtained by assembling shorter members by using the match casting technique in combination with posttensioning. In addition, the use of UHPFRC has allowed manufacturing durable elements, despite the limited thickness used and the high slenderness of the beams.
