Cables can be used to create highly efficient long span structures. In their simplest and most elegant form these types of the structure are often the most complex to analyse. And yet they are often the most intuitive and instinctive solutions. The graceful curve of the main cables of a suspension bridge is almost a catenary, the shape assumed by any string or cable suspended freely between two points. The conceptual simplicity of a tennis racket roof or flat cable façade poses a complex challenge for the Engineer.
Terrell understand cables and have a first class track record in the design of tension structures. We have developed our own specialised nonlinear form finding applications that are used to model the design and assembly of cable structures.
We strive to produce real tension structures that utilise the geometric stiffness of a pre-tensioned member to the full, using the pre-stiffening effects of selfweight to lighten the solution whilst maintaining a sensible balance between the forces internal to the cable structure and the reactions imposed on the supporting structure.
Some of the many examples of our work include the wall of glass of the Emirs Pavilion at Doha International Airport, the 70m span inverted catenary atrium roofs of the Ecole Nationale des Ponts et Chaussées, the tennis racket roof over the atrium of the building 40-46 rue de Courcelles, Paris, and the flat cable facades of the Radio Dansk Concert Hall and Recording Studios in Copenhagen.
