摘要：以位于8度区(0.30g)的某13层RC框架-剪力墙结构作为研究对象，基于《建筑抗震韧性评价标准》(GB/T 38591—2020),对其减震前后的抗震韧性水准进行了对比分析。结果表明：结构在减震前的抗震韧性等级为零星，修复时间控制了韧性等级，加速度敏感型非结构构件的修复费用主导了总修复费用，结构构件的修复时间主导了总修复时间；采用黏滞阻尼器减震技术后，结构在大震下最大层间位移角和楼面绝对加速度峰值分别降低了23.5%和16.8%;结构构件的损伤得到控制，从而有效控制了结构构件的修复时间，结构抗震韧性等级提升至一星。虽然减震后的楼面绝对加速度也得到了较好的控制，但仍高于加速度敏感型非结构构件的损伤阈值，导致减震前后该类构件的修复时间和修复费用变化不大。

Abstract: A RC frame-shear wall structure with 13 stories located in the 8 degree(0.30g) region was selected as the research object, based on Standard for seismic resilience assessment of buildings(GB/T 38591—2020),the seismic resilience level of the structure before and after seismic reduction were compared and analyzed. The results indicate that the seismic resilience level of the structure before seismic reduction is zero star. The resilience level is controlled by repair time, the repair cost of acceleration-sensitive non-structural components(ASNSCs) dominates the total repair cost, the repair time of structural components dominates the total repair time. After using the viscous damper seismic reduction technology, the maximum inter-story drift angle and floor absolute acceleration peak value of the structure under rare earthquake are reduced by 23.5% and 16.8% respectively. The damage of structural components is controlled, so that the repair time of structural members is effectively controlled, and the seismic resilience level of the structure is improved to one star. Although the floor absolute acceleration after seismic reduction is also well controlled, it remains much larger than the damage threshold of ASNSCs, resulting in slight change of the repair time and repair cost of such components before and after seismic reduction.
