Abstract: A broadcasting and TV center is a RC frame building. It consists of 2-4 stories and an air defence basement for conventional weapons. According to architectural functions, varied structural types are utilized. The structure design of piled foundation, air defence basement, steel tube confined concrete, RC truss, long span prestressed concrete beam, cost-in-situ hollow concrete floor are introduced. Points for attention of construction are also introduced.
