A tensile structure is a type of architectural design that relies on tension to support loads. These structures are typically made from flexible materials like fabric or cables, which are stretched between points to create a stable form. The tension in the materials allows them to efficiently distribute forces, making them lightweight yet strong. Commonly used in outdoor spaces, tensile structures can be seen in structures like canopies, sports arenas, and exhibition halls. They are valued for their aesthetic appeal and ability to create large, open spaces without the need for extensive support systems. Examples include the Millennium Dome in London and the Sydney Opera House.
