摘要

Concrete filled steel tube is a component formed by filling concrete in steel pipe. Compared with reinforced concrete, it has the characteristics of high bearing capacity, good plasticity and toughness, simple construction and greatly shortening the construction period. In order to study the axial compression performance of concrete filled steel tubular columns after fire, it is of great significance to the fire resistance design and post fire evaluation. This paper will summarize the research status of the mechanical properties of the Special‐shaped columns of concrete filled steel tubular in China.
