Case Studies and Applied Products
TENSA®FLEX RC – Sliding Finger joints
The Tensa®Flex slip finger can assimilate both horizontal and vertical movements and torsions. Modular structure makes possible the replacement of the system with minimum traffic interferences.
[more]Notes
The innovative design of the Lully viaduct proposes a light and transparent structure made of a triangular cross-section fabricated entirely from unstiffened circular tubes. The result is twin space trusses, with a typical span of 42.75 m. Each transversal triangular cross-section is 2.9 m high and 4.0 m wide, and is supported by a single slender pier. The largest diameters and thickness of the tubes are over 500 mm and nearly 70 mm respectively. Welded overlap K-joints and KK-joints form the brace-to-chord connections along the top and the bottom chords, respectively. The deck slab is connected directly to the top chord by uniformly distributed welded shear connectors.
