Abstract: The Miles Stair is a UHPFRC helical staircase designed by the architect Eva Jiricna for the Somerset House Trust in London. Wrapping around a steel-mesh newel, the staircase goes through the five-story of the West Wing of the museum from mid basement to 4th floor reaching 19,7m in height. Staircases are functional elements, but they cannot be reduced only to their functional uses, and often they become architectural masterpieces. Especially the helical stairs which fascinated designers and builders like Leonardo da Vinci or Oscar Niemeyer. The entire Miles Stairs is the assembly of precast elements in reinforced Ductal® with organic fibres. The design is a compromise between the technical requirements, the functional conditions and the building’s context. This paper starts with a presentation of the project of Eva Jiricna. Then the static behaviour of the structure and the design of the connections are presented. After that, the paper describes the technical details and explains why the UHPFRC was chosen and why it fitted perfectly for this project. In conclusion, a reflection is made on the feedbacks of this project.
