［摘要］建筑抗震韧性评价是地震工程领域的研究热点，对于引导业主和设计人员主动加强建筑抵御地震灾害的能力有重要意义。基于《建筑抗震韧性评价标准》（GB/T 38591—2020）开发了配套的建筑抗震韧性评价软件，并采用该软件对6栋钢筋混凝土建筑进行了韧性评价。结果显示：相对于抗震结构和消能减震建筑，隔震建筑更容易获得较高的抗震韧性等级；上部结构不进行降度设计的隔震建筑可以达到抗震韧性三星级，采用降度设计的隔震建筑基本可以达到抗震韧性二星级，消能减震建筑和抗震性能较好的抗震建筑可以达到抗震韧性一星级；按照现行抗震设计规范下限进行设计的抗震建筑不能满足抗震韧性一星级的要求。对于抗震和消能减震建筑，非结构构件的抗震性能对建筑物抗震韧性的影响显著。

Abstract:Seismic resilience assessment of buildings has become a research hot topic in earthquake engineering community, which has a  great significance to guide owners and designers to actively enhance the aseismic performance of buildings. A seismic resilience assessment software has also been development based on the   Standard for seismic resilience assessment of buildings(GB/T 38591—2020), and the software was used to evaluate the resilience of 6 reinforced concrete buildings. It is found that the base-isolated buildings are much easier to get higher seismic resilience rank compared with conventional seismic resistant buildings and energy dissipation buildings. Energy dissipation buildings that the superstructures designed without considering seismic force reduction effects can achieve three stars seismic resilience. Energy dissipation buildings designed with considering seismic force reduction effects can basically achieve two stars seismic resilience, and energy dissipation and seismic resistant buildings with good seismic performance can achieve one star seismic resilience. Seismic resistant buildings designed according to the lower limit of the current seismic design code cannot meet the requirements of one star seismic resilience. For seismic and energy dissipation buildings, the seismic performance of non-structural components has a significant effect on the seismic resilience of buildings.
