摘　　要：针对两栋分别按照美国规范和中国规范进行设计的42层典型钢筋混凝土框架-核心筒建筑,采用美国FEMA P-58建议的新一代抗震性能评估方法,仔细对比研究了按照中美规范设计的建筑在地震下的经济损失、修复时间和人员伤亡情况。结果表明,两国设计方案的地震损失情况存在一定差异,非结构构件的基于性能抗震设计需要得到进一步重视,同时FEMA P-58提出的抗震性能评估方法较传统方法更加直观,结果易于理解,为建筑可恢复功能抗震设计的研究提供了一定的参考。Seismic loss assessment of two RC frame-core tube buildings respectively designed according to Chinese and US codes were systematically conducted. In terms of economic losses,repair time and casualties,the loss assessments of these two buildings under earthquakes were performed and compared using the new-generation seismic performance assessment method provided by FEMA P-58 in the USA. The analysis results indicate that there exists a certain extent differences between the seismic loss of these two buildings,and more attention should be paid to the performance-based seismic design of nonstructural components. In addition,the seismic performance assessment method of FEMA P-58 is more intuitive and understandable compared with the conventional method. The research outcome will provide a useful reference for the research of resilience-based earthquake design of buildings.
