摘　　要：盱眙淮河明珠塔是采用钢结构空间结构体系,内外筒的连接靠水平、斜向支撑和混凝土板的共同作用形成。整个结构中部直径最宽,顶部和底部变细,使结构外筒稳定性变得较为复杂。而且,除塔底部、中部、顶部的功能层有较好的结构支撑和连接外,其他部分的连接相对比较薄弱。尤其是底部和中部之间的透空段,高度大、荷载大,因此这一段的群柱稳定性成为控制结构安全的重要因素之一。本文对该段结构进行了整体稳定性屈曲分析研究。同时也考虑了几何非线性对结构整体稳定性的影响。The structure system of Xuyi Tower is called as steel structure system.The connections between inner and outer steel tube rely on the combined action of horizontal and diagonal braces and concrete floor. At the same time,apart from functional floors in the bottom,middle and top,the connections of other parts of the tower is comparably weak,especially in the see-through region between the bottom and middle.The stability of columns,with high altitude and bearing great axial load,is one of the important factors for structure safety control.The buckling analysis of overall stability of this part of the structure is studied in,this paper, considering the impact of geometric nonlinearity on the overall stability of the structure.
