Cable supported structures are well used in modern architecture; not only can cables offer very attractive design possibilities, but cables also offer possibilities that are unable to achieve with steel or concrete. Cable structures are light and elegant. Whether bridges, roof structures, towers or an observation wheel; each construction demands high standards regarding dimensional accuracy, design, production and erection. The know-how of FibreMax with respect to cable constructions, characteristics, cable behaviour, end fittings, dimensions and tolerances as well as our experience, helps engineers and designers in the planning and designing of cable supported structures.

Cable-stayed bridges or suspension bridges are especially economical for medium to long-span bridges from 100 to 3500 meters. For smaller bridges, like footbridges, a cable stayed solution might be the choice just for weight reduction or aesthetical reasons. FibreMax lightweight precision cables are the right choice for the cables.

Also towers for telecommunication or antennas can be stabilized using FibreMax lightweight precision cables; ease of handling, non corrosive properties and the lack of electrical conduction make them ideal for these applications.

FibreMax can provide the bridge engineering or structural engineering industry with cables that suit their most demanding requests. The choice of FibreMax lightweight precision cables for these applications is based on the following characteristics:

  • 80 to 90% lower weight than steel wire *).
  • 10% lower diameters than steel wire *).
  • No construction stretch.
  • Exact lengths; length tolerance
  • Lifespan up to 40 years  (depending on usage).
  • Maintenance free.
  • No electrical conduction.
  • Higher natural frequency.
  • Ease of handling.

(*) When compared at the same break load).

Cables produced by FibreMax are available in any diameter and length. The increased strength and significant weight reduction over traditional material as steel offer many advantages in easier handling, safer and faster operations and downsizing of constructions.

Examples for typical FibreMax applications are:

  • Cable-stayed bridges.
  • Suspension bridges.
  • Tied arch bridges.
  • Cable stayed roof structures.
  • Office buildings, airport terminals or other modern art structures.
  • Observation wheels.
  • Guyed towers and antennas.
  • Tension members.
  • Stationary cables for skilifts.
Bridges

FibreMax can provide infrastructure companies, architects, designers and construction manufacturers with guy cables that suit their most demanding request. Guy cables of FibreMax can be used in suspension bridges and cable stayed bridges. FibreMax guy cables are especially of interest for suspensions bridges since as the span length of a suspension bridge increases, the weight of the main cables will increase in relation to the total weight of the suspended structure and a higher percentage of the cable stress will therefore be related to the self-weight of the cables themselves. With lightweight cables of FibreMax this stress will be greatly reduced.

Antenna

Towers for telecommunication or antennas can be stabilized using FibreMax lightweight precision guy cables; ease of handling, non corrosive properties and the lack of electrical conduction make them ideal for these applications. Antenna guy cables from FibreMax are mainly produced with aramid fibres. Aramid fibres have excellent dielectric properties and very low-to-zero creep properties which make them an ideal solution for telecommunication tower guys. Aramid guy cables have a low weight compared to steel (up to 90% less) which creates less tension in the supported tower thus enabling the use of more transmitters.

Roofing

Cable supported roofs are well used in modern architecture; not only can cables offer very attractive design possibilities, but cables also offer possibilities that are unable to achieve with steel or concrete. Cable supported roofs are light and elegant. Cable-stayed roof structures can create dramatic structures that enclose large volume column-free spaces, and still provide opportunities for architectural design freedom.

Tensile structures

With tensile membrane structures it is possible to realize unique, iconic and elegant structures due to the unique flexible characteristics of the membrane. The lightweight nature of membrane is a cost effective solution that requires less structural steel to support the roof compared to conventional building materials, enabling long spans of column-free space. Tensile structures are supported by pretensioned guy cables. Pretension is tension artificially induced in the structural elements in addition to any self-weight or imposed loads they may carry. It is used to ensure that the normally very flexible structural elements remain stiff under all possible loads. FibreMax offers light weight cables that can be used to pretension the flexible structural elements.
