摘　　要：为研究黏滞阻尼器对钢筋混凝土(reinforced concrete,RC)框架结构抗震韧性影响,基于增量动力时程分析方法,对附设黏滞阻尼器的RC框架结构开展抗震韧性能力评估。结合FEMA P-58以及我国抗震韧性评价标准,将主要受损构件的修复费用、修复时间曲线以及易损性信息按实际情况进行相应修正,并对无控结构和有控结构的修复费用、修复时间和人员伤亡等主要抗震韧性指标进行对比分析,明确了黏滞阻尼器对RC框架结构抗震韧性的影响。研究表明,在RC框架结构中适当设置黏滞阻尼器不仅能够减小结构地震响应、降低结构破坏概率,还能有效提升结构抗震韧性。In order to study the influences of viscous dampers on the seismic resilience of reinforced concrete(RC)frame structures,the seismic resilience assessment of a RC frame structure with viscous damper was carried out based on the incremental dynamic time history analysis method.Combinedly considering the FEMA P-58 and Chinese seismic resilience assessment standards,the repair cost,repair time curve and fragility information of the main damaged components were modified accordingly,also the main seismic resilience indicators such as the repair cost,repair time,and personnel casualties of the uncontrolled structure were analysed and compared with the controlled structure to clarify the influences of the viscous damper on the seismic resilience of the RC frame structure.The results show that setting up viscous dampers properly in the RC frame structure can not only reduce the seismic response of the structure,lower the probability of structural failure,but also effectively improve the seismic resilience of the structure.
