摘　　要：选定两个模型,假定了8个算例,输入代表不同场地条件的5条典型地震波,应用有限元分析方法,对不同计算方案的算例进行三维弹性地震时程反应分析。通过对不同计算方案结果的比较,分析梁的设置对层间位移的影响,为进一步深入研究巨型钢结构的抗震性能及抗震设计提供基础。Two mega steel structures are selected as examples, eight analytical models are hypothesized, and five typical earthquake waves are selected, which represent different site conditions. Using finite element analysis method, three-dlmensional elastic history time analysis of three mega steel-frame structures with different analytical models subjected to different earthquake ground motions are conducted. In order to study influence of sto- ry-drift from beam number, the results of different examples are compared, The conclusions obtained lay foundation for studying the seismic performance and seismic design of mega structures Drofoundly.
