Abstract: In order to accurately and efficiently evaluate the static and dynamic behavior of steel-concrete frame structure in hydropower station in high frequency and high intensity earthquake area, this research focuses on the composite service performance test and mechanism analysis of steel tubular composite columns, the service performance test and theoretical analysis of steel-concrete composite floors, the service performance and safety bearing analysis test and mechanism analysis of steel-concrete composite joints, the static and dynamic service performance research of steel-concrete composite frame structure, the impact service performance research of steel-concrete composite frame structure, and the large-scale combination optimization analysis of service performance of frame structure. In this paper, the research methods of the service behavior of the frame structure of the hydropower station, the research progress of the reinforced concrete structure of the hydropower station and the steel-concrete frame structure of the hydropower station are summarized. This paper also summarizes the development of steel-concrete composite structure in the hydropower plant frame structure, the existing problems in the engineering application and the research work to be promoted, which is to study the service performance improvement and safety guarantee technology of the hydropower plant structure.
