Structure Design of Guangdong Broadcast Center/Chen Changqing (The Architectural Design and Research Institute of Guangdong Province,Guangzhou 510010,China)

Abstract:Guangdong broadcast center is a key project of Guangdong province. Artificial pile foundation set into rock，skirt building with prestress plane floor and tower building with steel reinforced concrete(SRC) structure are adopted in the project. After the introduction of transfer beam， roof antenna and the construction of concrete joints for both firstandsecond phases，effective measures of crack control in massive concrete construction are introduced with the sample of transfer beams.

Keywords: prestress plane floor; steel reinforced concrete(SRC); transfer beam; massive concrete; crack-control measures
