Stainless steel has the advantages of good appearance, excellent mechanical properties, strong corrosion resistance, easy maintenance and low life-cycle cost. It is widely applied in the field of construction and has wide application prospects. Stainless steel structures have their irreplaceable applicability in marine engineering. Meanwhile, for the architectural constructions in acid-rain-prone areas, because of its superior corrosion resistance, stainless steel structure has excellent performance in saving building maintenance costs and prolonging construction life-cycle. Stainless steel materials have been gradually developed from decorative components to structural load-bearing main components, which have been widely used in civil engineering [1, 2]. However, in recent years, building fires have occurred frequently, and unprecedented challenges are being faced with regard to the safety of building structures in fire. As a building structural material, stainless steel structures or components often do not use any fire prevention measures due to attempts to obtain a good appearance effect. Therefore, the behaviour response and mechanical behaviour of stainless steel structures in fire are particularly important. Alternately, the structure in fire often has a strong integrity. There are quite complex interactions and internal force redistributions between each component. Therefore, it is of great theoretical value to study the fire resistance performance of stainless steel columns with constraints. 17There are many studies on the behaviour response and fire resistance of constrained carbon steel 18 columns in fire. The main contents are the mechanical properties and buckling temperature of constrained steel columns in fire. Neves et al. [3, 4] used the ZWAN program to carry out numerical simulation analysis of the fire resistance of axially constrained steel columns, and a simple analysis model of the fire resistance of steel columns is proposed.
