Civil Engineering Cables

The world’s longest stress ribbon bridge was awarded with the JEC Innovation Award 2012 in the construction category. Future Fibres provided carbon fibre cables as the primary load-bearing supports of this bridge structure built in Cuenca, Spain.

The final design involved 16 lines of cables, laid side by side, to achieve the required 216m long, 3m wide bridge. Each of the eighty, 43.4m long, carbon cables had a working load of approximately 95 tonnes, a diameter of 42mm and weighed in at less than 100kg each.

Future Fibres’ innovative composite solution enabled Acciona Infrastructures design team to conceive a distinctive, contemporary design for this bridge; one which would not have been possible with standard building materials. Unsupported spans were significantly increased, supporting structure was reduced and installation time and, most importantly, cost were reduced by over 80%.
