摘　　要：将超高层建筑空间巨型框架结构等效连续化为一个加劲薄壁筒的组合体,以此空间三维模型,用半解析法对超高层建筑空间巨型框架结构进行了自由振动分析计算.结果表明,这种简化分析方法是有效、合理的.In the paper, super high_rise building space_mega_frame structures are simplified equivalently and continuously to a three_dimensional model, which is a combination of stiffened_thin_wall tubes. And free vibration analysis of a super high_rise building space_mega_frame structure was made by using semi_analytical method based on the three dimensional model. The effectiveness and rationality of the method were verified through a numerical example.
