Abstract:An office building in Longhu Financial Center in Zhengdong New District adopts frame-corewall structural system. The floor and roof adopt cast-in-situ concrete hollow floor technology. The foundation design,  structural system and scheme selection,  hollow floor design and construction detail,  and connection structure of column-slim beam were introduced in detail. The cast-in-situ hollow slab uses packing box and light pipe as the filler and the volumetric void ratio of 400mm thick hollow floor reached 46-8%. The calculation of reinforcement and deflection of the hollow floor were introduced. 

Keywords:structural system; cast-in-site concrete hollow floor; slim beam; filler; core area structure
