摘要
对超高层建筑空间巨型框架的振动计算提出一个新的简化计算模型 ,将空间巨型框架简化为巨型柱和弹性地基上的巨型梁的组合 (二级框架柱考虑其轴向变形作为巨型梁的弹性地基 ) ,按空间刚架进行刚度分析 ;建筑物的质量集中于巨型梁的楼层 ,是一种新的简化的空间杆系 层模型。
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 huge columns 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.
