摘　　要：为确保重大建设工程满足地震时正常使用建筑的要求,研究了广州白云国际机场三号航站楼的抗震性能。通过抗震性能设计,确定花冠状分叉柱大震弹性性能目标,结合超长结构的多点多维地震响应分析,研究行波效应对主体结构的影响并确定相应的加强措施,边柱和角柱的地震力放大系数取1.3,中柱取1.1。计算结果表明,结构在1.5倍设防地震作用下,最大弹性层间位移角不大于1/300,满足地震时正常使用的抗震性能要求。In order to ensure that major construction projects meet the normal use requirements of buildings during earthquakes,the seismic performance of Guangzhou Baiyun International Airport Terminal 3 was studied.Through the seismic performance design,the elastic performance target of the corolla bifurcated column under large earthquakes was determined.Combined with the multi-point and multi-dimension seismic response analysis of the super-long structure,the influence of the traveling wave effect on the main structure was studied and the corresponding strengthening measures were determined.The seismic force amplification factor of the side column and the corner column is 1.3,and the center column is 1.1.The calculation results shows that under the action of 1.5 times the fortification earthquake,the maximum elastic interstory displacement angle is not more than 1/300,which meets the seismic performance requirements for normal use during earthquakes.
