随着韧性城市建设的需求,结构抗震韧性研究成为热点话题之一.本文主要论述城市抗震韧性的应用研究进展,指出由单一建筑到群体建筑的抗震韧性研究趋势;阐述医疗建筑结构抗震韧性研究进展,生命线式的医疗建筑应考虑减震、隔震等技术的迫切需求;在抗震韧性评价中量化抗震韧性评价指标,以损伤恢复指标、恢复曲线积分指标、其他指标为主,确定损伤构件对结构的影响是研究趋势;针对不同抗震韧性评估方法对结构抗震韧性评价进行对比,构建综合评价指标,以满足评价需求.在抗震减灾形式下,依据震损结构的研究基础,对于新建建筑和既有建筑加固、改造等提高结构韧性性能提出了更高的要求,为抗震韧性的研究提供了参考,也是当今低碳建筑的发展需求.
With the demand for resilient urban construction,research on structural seismic resilience is also a hot topic.The application research progress of urban seismic resilience is discussed,and the research trend of seismic resilience from single buildings to group buildings is pointed out.This article elaborates on the research progress of structural seismic resilience in medical buildings,and the urgent needs of seismic absorption,isolation,and other technologies should be considered for lifeline style medical buildings.Quantifying seismic resilience evaluation indicators in seismic resilience evaluation mainly focus on damage recovery indicators,recovery curve integration indicators,and other indicators,to determine damaged components.The impact of damaged components on the structure is a research trend;Comparing the seismic resilience evaluation of structures with different seismic resilience evaluation methods,comprehensive evaluation indicators are constructed to meet the evaluation needs.In the form of earthquake resistance and disaster reduction,based on the research foundation of earthquake damaged structures,the demand for improving the structural toughness performance of new and existing buildings such as reinforcement and renovation provides a reference for the research of earthquake resistance toughness,and is also a development demand for low-carbon buildings today.
