ABSTRACT

As a new type of composite member, concrete-filled aluminum alloy tubular (CFAT) columns combine the dual advantages of low self-weight and excellent corrosion resistance of aluminum alloy with the outstanding compressive performance of concrete, showing broad application prospects in modern building structures. Fire is one of the major hazards faced by building structures. Due to the low melting point of aluminum alloy and the deterioration of concrete properties at elevated temperatures, the fire resistance of such members has become a critical issue that urgently needs to be addressed in engineering applications. This paper systematically reviews the research progress on the fire resistance of CFAT columns at home and abroad. It summarizes the existing research achievements from three dimensions: the mechanical performance of CFAT columns at ambient temperature, the high-temperature properties of aluminum alloy materials, and the fire resistance of aluminum alloy structures. Special emphasis is placed on analyzing the influence of factors such as cross-sectional configuration, material parameters, load ratio, and fire exposure conditions on the fire resistance of the members. The applicability and limitations of existing high-temperature material constitutive models and thermo-mechanical coupling analysis methods are discussed, and the current problems in the research are summarized. Finally, combined with the requirements of engineering applications, future research directions on the fire resistance of CFAT columns are prospected, aiming to provide references for the fire-resistant design and engineering application of such members.
