Abstract
Research on the mechanical properties of concrete-filled steel tube composite frames at high temperatures is one of the current hot issues. In this paper, the finite element simulation software is used to analyze the concrete-filled steel tube composite frame, introduce the failure mode of the concrete-filled steel tube composite frame under high temperature, and deeply study the simulation results of the single-story mechanical performance. The single-span concrete-filled steel tube composite frame structure based on the analysis of the concrete-filled steel tube bearing capacity, including the role of each beam and column in different temperature fields, structural fields and coupling fields, as well as the role in the entire section. As the temperature increases and decreases, its mechanical properties will change significantly under the action of concentrated loads. The bearing capacity of the composite frame at high temperature is somewhat lower than that at room temperature. The research results can provide a reference for the reinforcement and repair of the steel tube concrete composite frame under high temperature.
