Abstract

Concrete filled steel tube column (CFST) combined with reinforced concrete (RC) flat slab provides potential structural solution to replace the traditional structures in high-rise buildings. The CFST column – RC slab connection is the key factor for this structure type to work effectively. This paper proposes an improved structure for connection of concrete filled steel tube column and reinforced concrete flat slabs using steel plate shear-head. The experiments of two large-sized specimens are performed to assess the capacity and reliability of the proposed connection. Numerical simulation using Abaqus is also performed to validate the test results. Based on experimental and numerical simulation results, an analytical prediction model to estimate the punching shear capacity of the flat slab is presented.
