Relating to structural systems that work primarily in tension, such as cables, membranes, or fabric structures that are pulled taut rather than compressed. These systems create lightweight, spanning structures through tensioned elements.
From Latin 'tensus' (stretched), entering English in the 17th century from physics and engineering. Architectural application expanded in the 20th century with new materials like high-strength steel cables and synthetic fabrics.
Frei Otto's Munich Olympic Stadium roof looks like a giant spider web or sailboat rigging - those steel cables and acrylic panels create a structure that's incredibly light yet spans enormous distances. Tensile structures prove that architecture can be gossamer-light while still providing shelter, opening up possibilities for temporary and adaptable buildings.
