Structural design for center Hall in IFEZ Arts Center

Abstract

The concert hall of big scaled building for Arts Center, is located on IFEZ (Inchon Free Economic Zone) G2-1 Block. It comprises of 7 floors and 2 basements. This paper represents the structural design of the building and the methods being issued which protect from floor vibration and noise effects. Another issue item is to make large span hall and cantilever. At first time, we proposed to use the super-column supported roof trusses. But these super-columns had some problems of architectural module, economics and constructability. It is lied large span trusses at roof and 7th floor, and the roof truss has a large cantilever about 40m. Trusses are supported by core walls and SRC columns. For reduce the displacement of truss, we proposed the rigid joint of the connection of truss at edge core walls. It is occurred a big member force at this joint, and then we proposed the embedded plate in the core wall. It is experienced the structural design of concert hall as music hall, because the structural designer engaged floor vibration and also acoustic parts.
