A structural system consisting of cables arranged in a grid pattern to support roofs or facades, with loads transferred through the network of tensioned cables. Cable nets can cover large spans with minimal material while creating dramatic curved surfaces.
From 'cable' (steel wire rope) and 'net' (network pattern), terminology developed in the 1960s as engineers explored tension structures. The concept was influenced by tent and sail construction principles.
The Munich Olympic Stadium's revolutionary cable-net roof was inspired by spider webs and soap films - architect Frei Otto studied how nature creates minimal surfaces with maximum efficiency! The transparent acrylic panels hung from the cable net created the illusion of a crystalline landscape.
