Application on Concrete-filled Steel Tube Composite Structure in the Field of Civil Engineering

In recent years, as the construction technology tends to mature, the engineering field has higher and higher requirements for structures in engineering, and the composite structure has gradually become a hot spot. This paper focuses on the study of concrete-filled steel tube (CFST) structures in composite structures. By studying the development process of CFST structure and the production process in the actual project, it is proved that the composite structure of CFST has more research prospects than the traditional structure. Then, it is analyzed that CFST has many advantages, and the application prospect in the future practical engineering is more extensive than the traditional structure. Then the existing cases of CFST structure in various aspects of engineering are listed, the role of using CFST structure in Nanchang Shengmi Bridge is analyzed. The conclusion is drawn that the composite structure including CFST has the tendency to replace the traditional structure. This paper aims to provide a possible reference for the future research of CFST.
