摘　　要：城市结构是城市抵御地震灾害的关键载体,其抗震韧性要求在地震作用下具有快速恢复结构使用功能的能力。通过抗震韧性评估定量反映结构地震损伤及恢复程度,可为制定城市结构韧性提升策略提供依据。本文系统地梳理了城市结构抗震韧性评估研究现状。首先,介绍了结构抗震韧性的基本理念,从韧性指标、韧性模型、韧性水平及韧性评估四个方面总结了国内外关于城市结构抗震韧性评估的研究成果;其次,探讨了城市结构抗震韧性评估的发展趋势。已有研究表明:结构抗震韧性评估的研究在评估方法高效化和韧性模型精细化方面取得了较大进展,但仍然面临功能恢复模型不完善和韧性评估工程实践案例较少等诸多挑战;最后,对未来研究方向进行了展望,可为后续城市结构抗震韧性评估研究提供参考。The urban structure is a crucial carrier for cities to resist earthquake disasters,and its seismic resilience requires the ability to quickly restore structural usability under earthquake action.Through seismic resilience assessment,the structural earthquake damage and recovery level can be quantitatively reflected,which can provide a basis for formulating strategies to enhance the resilience of urban structures.This article aims to systematically review the current research status of urban structural seismic resilience assessment.Firstly,the basic concept of structural seismic resilience is introduced,and the research results of urban structural seismic resilience assessment are summarized from four aspects:resilience indicators,resilience models,resilience levels,and resilience assessment in domestic and foreign studies.Secondly,the development trend of urban structural seismic resilience assessment is discussed.Previous studies have shown that research on structural seismic resilience assessment has made significant progress in efficient assessment methods and sophisticated resilience models,but still faces many challenges,such as a lack of resilience assessment engineering practice cases and imperfect function recovery models.Finally,future research directions are discussed to provide references for subsequent urban structural seismic resilience assessment research.
