Abstract:

The experimental Roize Bridge, near Grenoble, France, features an innovative composite space truss and unique modular construction methods for efficiency and economy. The Roize Bridge consists of three spans: two 118 ft end sections and a 131 ft long center span. Deck geometry places the structure on a 1,755 ft radial spiral, with a variable cross slope from 0% to 3.5%. A precast concrete deck slab supported by a steel space truss make up the composite superstructure. The space truss is unique, composed of a single hexagonal lower flange, two inclined Warren-type trusses and transverse floor beams spaced 13 ft apart. Each precast deck slab is 40 ft wide and 12 ft 4 in. long. The slabs are supported by the transverse floor beams and are connected by a transverse closure pour. The bridge is posttensioned with continuous draped tendons over the three spans. Concrete piles 40-50 ft long support the bridge structure, with a total of three 40 in. diameter piles under each abutment and two 50 in. diameter piles beneath each of the intermediate piers.
