along with Membrane structure landscape With the development of building installation technology, design numerical analysis theory and method, membrane structure landscape system is evolving and upgrading, including inflatable membrane, tension membrane and new membrane structure system.
Air supported inflatable membrane: In 1917, the British W. Lanehester invented an inflatable membrane as the roof of the outdoor hospital building, which is a modern roof system with convenient installation and economical cost Membrane structure landscape architecture , but he didn't build it himself.
In 1946, Walter Bird, an American, used glass fiber based neoprene as the coating material to build the first modern inflatable membrane structure DopplerRadome, with a diameter of 15 meters and a height of 18.3 meters. From 1950 to 1970, the United States, Germany and other places successively built a large number of similar domes with a diameter of 60 mt.
In 1970, the World Expo in Osaka, Japan provided an opportunity for the development of membrane structure landscape. Due to frequent earthquakes in Japan, most of the exhibition halls are located on soft soil foundation, so the exhibition hall should adopt light structural system. A large span, low profile (small height) air support membrane is designed by David Gai at the head of the USA Pavilion. The plane is an ellipse of 13978m, and the membrane is Grade B.
From 1972 to 1984, Bird Airways, designed by David Geiger, built seven large air support membrane structures in the United States, including the silver dome (220mm 159m), but most membrane domes proved difficult to effectively resist severe weather conditions and maintain normal use. In 1985, the silver dome was almost completely destroyed by strong winds and snowstorms.
In 1988, Japan built the Tokyo Dome. Although the technology of air supported membrane structure has developed to a new stage, since then, no large-scale air supported public membrane structure landscape architecture has been built in the world. Before the cable dome system appeared, the air supported membrane structure created a long-span membrane structure Scenery The glorious development history of architecture.
