[提要] 對超高層建筑空間巨型框架的振動計算提出一個新的簡化計算模型，將空間巨型框架簡化為巨型柱和彈性地基上的巨型梁的組合（二級框架柱考慮其軸向變形作為巨型梁的彈性地基），按空間剛架進行剛度分析；建筑物的質(zhì)量集中于巨型梁的樓層，是一種新的簡化的空間桿系-層模型。為超高層建筑空間巨型框架的振動分析提供一個合理可行的算法。
[關(guān)鍵詞] 空間巨型框架 彈性地基梁單元 桿系-層模型 振動分析A new simplified computational model for dynamical analysis of extra tall building structure space mega-frame is established. The computational model is space member system-storey model, the space mega-frame is composed of hugecolumns and huge beams on elastic foundation, the columns of the second frame, considering its axial deformations, are seen as the elastic foundation of the huge-beams, the masses are lumped on the huge-beams storeys. The new model is simple and rational.
Keywords: space mega-frame; beam element on elastic foundation; member system-storey model; dynamical analysis
