What buildings have been designed according to the principle of eggshells?

Shell structure can be made into a variety of shapes to adapt to the needs of the project shape, and therefore widely used in engineering structures, such as large-span building roof, small and medium-span roof panels, engineering structures and lining, a variety of industrial pipelines and cooling towers and cooling towers, reactor containment, radio towers, tanks and other liquid storage. Shells used in engineering structures are made of reinforced concrete, steel, wood, stone, brick or fiberglass.

China since the 1950s, with the shell structure built many practical, economical, beautiful housing construction, such as Urumqi City, a gold workshop diameter of 60 meters of ellipsoidal shell; Beijing train station hall 35 × 35 meters hyperbolic flat shell; Dalian port warehouse roof 16 23 × 23 meters combined twisted shell.

Beijing Great Hall of the People west of the "dome" - the National Grand Theater using shell structure. Its steel structure shell east-west span of 212.24 meters, north-south span of 143.64 meters.

Hangzhou Sibao sewage treatment plant in June 1999 built three egg-shaped digester with a volume of 10926m3 each. The maximum diameter of the egg-shaped body 24m, the upper and lower part of the circular platform body, the middle part of the radius of 24m, the arc of 85 degrees arc rotation and become the pool height of 32m, the hollow height of 41.7m, buried depth of 13.6m. using two-way non-bonded prestressed concrete structure.

Foreign buildings using shell structure are Barcelona St. Jordi Stadium, Germany Hanno swimming pool, Japan Yoyogi Arena, Lyon, France, and other train stations. Not listed.
