摘　　要：随着人们生活水平的提高,部分早期建设的高层建筑由于电梯数量已难以满足日常使用要求,需要加装新电梯。新增高层钢结构电梯井道高度较大且层数较多,其结构整体稳定问题颇为关键。本文基于实际工程,采用线性屈曲分析方法,对井道整体稳定性能、侧向约束影响、结构初始缺陷、井道支撑布置等问题进行了初步研究,得到了一些有益结论,可供同类工程参考。As the improvement of people living standards, the number of elevators of some early built tall buildings can not meet the requirement of daily use, so new added elevators are strongly needed. As the tall height and large floor number of tall elevator steel hoistway, the structural stability problem of this kind of structure is very critical. Based on actual project, the eigen buckling method is carried out for the preliminary analysis of structural stability, effects of lateral restraint, initial structural defect, brace setting of hoistway. Some useful conclusions are obtained in this paper for reference of similar projects.
