Membrane structure, also known as Tensioned Membrane structure, is a new type of architectural structure developed in the middle of 20th century.
Membrane structure is a kind of spatial structure which is made up of a variety of high-strength membrane materials and reinforcing members (steel frame, steel column or steel cable) to generate certain pre-tension stress in its interior in a certain way to form a certain spatial shape, which can be used as a covering structure and bear certain external load.
