Eine Plattform für die Wissenschaft: Bauingenieurwesen, Architektur und Urbanistik
A walkway 2 mounted to a surface comprises a plurality of support portions 6, at least one tunnel portion 14 and a walkway portion 20. The tunnel portion is connected between a pair of the support portions and comprises a plurality of interconnected tensile members placed under tension. At least one of the tunnel portions displays negative thermal expansion, and the walkway portion is located within the tunnel portion. Providing tunnel portions which display negative thermal expansion at least partially cancels expansion in the supports, minimising the requirements for bearings to accommodate expansion and contraction of the walkway. The walkway may be mounted on a cliff. At least one tunnel portion may include polyethylene and may be formed from a mesh of the tensile members. At least one support portion may include aluminium and may be pivotably mounted to the support surface at a first location and mounted by at least one tensile member 10 at a second location. The walkway may be mounted to the support portion by at least one hinged support.
