Abstract

The rectangular concrete-filled steel tubular column is a vertical bearing member, and it is easily damaged under the influence of the earthquake. Many reinforced concrete structures in China are in earthquake zones. When the load-bearing column is damaged and is not easy to repair, even if the structure does not collapse, it should be demolished and rebuilt. This paper discusses the destruction models of the earthquake to rectangular concrete-filled steel tubular column, analyzes the performance of rectangular concrete-filled steel tubular column under earthquake, and explores construction quality control and key technologies of the rectangular concrete-filled steel tubular column to provide some references for the relevant researchers.
