钢-混凝土组合结构在我国高烈度区逐渐得到广泛的应用,但目前国内外对其地震易损性研究很少。在分析总结现有结构地震易损性研究的基础上,阐述了组合结构地震易损性研究中亟待解决的两个关键问题,这些问题的研究和解决将对钢-混凝土组合结构的地震易损性的研究提供坚实的理论基础。 Steel-concrete composite structures have been widely used in high-intensity areas of our country, but few researches have been done on seismic fragility at home and abroad. On the basis of analyzing and summarizing the research on seismic vulnerability of existing structures, two key problems to be solved urgently in the study of seismic vulnerability of composite structures are expounded. The research and solution to these problems will make the seismic vulnerability of steel-concrete composite structures vulnerable Sexual research provides a solid theoretical basis.
