摘要
近年来吉林省松原地区破坏性地震频发,十分必要对当地群体建筑结构的抗震韧性进行分析。对吉林省松原地区的群体建筑结构进行地震响应分析以及抗震韧性评估,对比分析城市和乡镇群体建筑结构在地震作用下的地震响应和抗震韧性。根据《建筑抗震韧性评价标准(GBT 38591—2020)》确定群体建筑结构抗震韧性评估流程,通过韧性指数法和韧性等级法对群体建筑结构的抗震韧性进行定量分析,对城乡抗震韧性的评价结果为当地防震减灾提供理论支持。
In recent years,destructive earthquakes occurred frequently in Songyuan area,Jilin Province,so the seismic resilience of group structures in this area is necessary to be analyzed.The earthquake response and seismic resilience of group structures in cities and towns of Songyuan area were analyzed and compared in this paper.The evaluation process of seismic resilience of group structures was determined according to the Standard for Seismic Resilience Assessment of Buildings(GBT 38591-2020),and a quantitative analysis of the seismic resilience of group structures was conducted based on the resilience index method and the resilience grade method.The evaluation results of the seismic resilience of urban and rural buildings in the Songyuan area can provide a theoretical basis for local earthquake prevention and disaster mitigation.
