The ultimate load-bearing capacities of axially-loaded steel tube composite column filled with steel reinforced concrete under three-dimensional stress based on the unified strength theory are analyzed in this paper. The influence of thickness-length ratio and scale effect are considered by introducing the reduction factor of equivalent constraints and concrete strength reduction factor, respectively. The nonlinear three-dimensional finite element analysis of the steel tube composite column filled with steel reinforced concrete is performed by the finite element software ANSYS. The numerical and the analytical results are compared with experimental results and good agreement can be observed. A series of numerical simulation technologies is studied and described in detail, such as selecting element type, defining material model of steel and concrete, establishing global finite element model with discrete reinforced bars elements, applying loads to the specimens, and setting solution controls option. The results indicate that ANSYS finite element software may well simulate the behavior of the steel tube composite column filled with steel reinforced concrete under axial compression through reasonably selecting parameters.

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.
