Abstract: A combination of outstanding advantages of concrete filled steel tube (CFST) column with reinforced concrete (RC) flat slab creates the effective and potential structure to replace traditional reinforced concrete frame structures in high-rise buildings. The CFST column – RC slab connection is the key factor for this structure type to work properly and effectively. Currently, the studies mainly focus on inner CFST column and RC slab connection, there are very few experimental studies on connection of edge or corner CFST columns and RC flat slab. This paper proposes edge and corner CFST columns to RC flat slab connection structures using H-shaped shear head and then conducts two large size tests to investigate behaviors of the connection.
