• Abstract:
  Special shaped columns composed of concrete-filled square steel tubes have broad application prospects in steel structure residential buildings. The paper aims to discuss this issue. In this paper, the thermal bridge problem of special-shaped column structures is studied, T-shaped column composed of concrete-filled square steel tubes is taken as an example, the finite element thermal bridge model is established by ANSYS software, the heat treatment is calculated by the software and the results are output. According to the finite element results, it can be found that in the thermal bridge model, the temperature distribution is uniform, the heat flux density is small and the heat dissipation where the steel plate locates is serious. The lowest temperature of the thermal bridge is greater than the air condensation temperature, and the affected area is about 0.2 m, which is larger than the thickness of the wall and will not cause too much impact on the wall. It will help to suppress heat dissipation and achieve energy-saving and heat preservation inside the buildings. The experimental results prove the effectiveness of the special-shaped column structure for building energy-saving buildings. This study provides some theoretical basis for further application of special-shaped column structures in architecture.
