| 摘 要： | 本文以2个巨型钢框架结构作为算例,通过改变巨型梁数量和位置,假设了不同的结构计算方案,输入代表不同场地条件的5条典型地震动和4个场地类别的设计反应谱,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反应分析。通过对不同计算方案结果的比较分析,研究了巨型梁的数量和位置对巨型钢框架结构地震反应的影响,为进一步深入研究巨型钢结构的抗震性能及抗震设计方法提供基础。

| Abstract: | In this paper two steel mega-frame structures are selected as examples.By changing the quantity and location of mega beams,different analytical models are hypothesized.Five typical earthquake ground motions and design response spectra of four site classes are selected,which represent different site conditions respectively.Using finite element program,three-dimensional elastic seismic response analysis of examples with different analytical models is conducted.Comparing the results among different analytical models,the influence of the quantity and location of mega beams on the seismic responses of steel mega-frame structures is studied,which lays a foundation for further studying seismic behavior and seismic design method of steel megaframe structures. |
