Abstract： Large public buildings are not only an infrastructure system to guarantee post-earthquake disaster relief and urban system functional recovery, but also an important hazard bearing body for earthquake disasters. Once an earthquake occurs, it will cause a serious earthquake disaster of the nonstructural components in the large public buildings, and then affect the use function of buildings, lead to huge economic losses, and even pose potential threats to the evacuation and resettlement of people. This paper systematically summarizes the research progress of seismic performance analysis methods for nonstructural components from three aspects: theoretical analysis, numerical simulation, and experimental research. Taking the suspended ceiling, curtain wall, and elevator as examples, the seismic response and failure characteristics of nonstructural components are described. This paper also discusses the new ideas of the research on the seismic performance of nonstructural components in the large public buildings. The seismic performance analysis methods of nonstructural components constantly innovate combining the development of material science, control science, and interdisciplinary research. The seismic damage assessment method and intelligent identification technology will be built based on big data and artificial intelligence technology. It will provide a basis for the seismic resilience evaluation of nonstructural components. The seismic resilience enhancement technology of nonstructural components will provide technical support for the safe operation of large public buildings.
