［摘要］北京A380机库跨度362.6m，是目前世界上单体规模最大的机库。配合工程结构设计，采用反应谱法、弹性时程分析法以及静力和动力弹塑性时程分析法，对大跨度机库在各阶段地震作用下的结构反应进行了分析，并考虑了行波效应的影响。分析结果表明，在罕遇地震作用下，结构整体刚度没有明显下降，整体受力状态尚未达到结构最大承载能力，机库结构设计达到了预定的抗震性能目标。同时，采用环境随机振动激励法对建成后该机库的动力特性进行了现场实测，获取了结构实际动力特性相关参数，与理论分析进行对比，从而进一步了解结构的抗震性态，验证机库结构在地震作用下的安全性。

Abstract:Beijing A380 hangar whose span is 362.6m, is the largest single hangar in the world. Using response spectrum method, elastic time-history analysis method, as well as static and dynamic elastic plastic time-history, analysis of large-span hangars in various stages of the structure under earthquake response is performed and the traveling wave effects are considered. The results show that, under the rare earthquake, the overall stiffness of the structure has no obvious drop, and the structure has not yet reached the maximum carrying capacity, the design of the aircraft  achieves the predetermined goal of seismic performance. Using the environment random vibration stimulating method on the dynamic performance of the completed aircraft, the actual dynamic characteristics of structural-related parameters are obtained and compared with the theoretical analysis in order to further understand the seismic behavior of the structure and to verify the safety of the hangar structure in seismic.
Keywords:Beijing A380 hangar; seismic response analysis; multi-point input; environment random vibration stimulating method; measured dynamic characteristics of the scene
