城市和建筑抗震韧性研究的进展与展望

Progress and prospect of research on seismic resilience of cities and buildings

抗震韧性设计的理念代表着当前结构抗震和城市防灾减灾领域的前沿方向,城市和建筑抗震韧性研究作为城市韧性研究的基础和减轻城市地震灾害的重要措施而备受关注,已成为国际地震工程领域和城市规划领域研究的热点问题之一。由于城市系统的复杂性和地震发生的不确定性,这一领域的若干科学问题还尚不明晰,亟待深入的研究和探索。文中总结和评述了当前城市及建筑抗震韧性研究的新进展;论述了抗震韧性研究的理论基础;梳理和厘定了城市及建筑抗震韧性的评价指标、评价方法及其定义和内涵;对这一领域未来的发展趋势和研究方向进行了探讨,并提出了具体的建议。城市和建筑地震安全的需求为这一领域的研究提供了广阔的空间和巨大的动力,城市和建筑抗震韧性研究必将极大地推动结构抗震和城市防灾减灾工作的创新和发展。文中的工作对从事结构抗震、防灾减灾和城市规划的科技人员有一定的参考价值。

Seismic resilience design represents the frontier direction in the field of seismic structures and urban disaster prevention and mitigation.The research on urban and buildings seismic resilience has attracted much atten⁃tion,and has become one of the hot issues in the field of international earthquake engineering and urban planning.Due to the complexity of urban system and the uncertainty of earthquake occurrence,some scientific problems in this field are still unclear and need further research and exploration.This paper summarizes and comments on the progress in the research of urban and buildings seismic resilience;discusses the theoretical basis of seismic resil⁃ience research,combs and determines the evaluation index,evaluation method,definition and connotation;dis⁃cusses the future development trend and research direction in this field,and puts forward specific suggestions.The demand of urban and building seismic safety provides a broad space and huge power for the research in this field.The research of urban and buildings seismic resilience will greatly promote the innovation and development of seis⁃mic structures and urban disaster prevention and mitigation.The work has a certain reference value for researchers in structural earthquake resistance,disaster prevention and mitigation and urban planning.
