摘要
大型公共建筑既是保障震后救灾及城市系统功能恢复的基础设施系统,又是地震灾害的重要承灾体。地震一旦发生,大型公共建筑中非结构构件会造成严重的地震灾害,影响建筑的使用功能、造成巨大的经济损失,甚至给人员疏散和安置带来潜在威胁。文章从理论分析、数值模拟及试验研究等3个方面系统总结非结构构件抗震性能分析方法的研究进展。以吊顶、幕墙及电梯为例阐述非结构构件的地震响应及破坏特征。探讨大型公共建筑中非结构构件抗震性能研究的新思路:结合材料科学、控制科学及交叉学科的发展,不断创新非结构构件的抗震性能分析方法;结合大数据和人工智能技术形成非结构构件震害评价方法和智能识别技术,为非结构构件的抗震韧性评估提供依据;发展非结构构件地震韧性提升技术,为大型公共建筑的安全运行提供技术保障。
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 non-structural 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.
