摘　　要：随着人们生活水平的提高,旧楼加装电梯的工程越来越普遍。对于观光电梯,井道外侧钢梁常采用弧形梁,而我国现行《钢结构设计规范》的计算长度系数法对弧梁钢框架结构并不适用。本文采用线性屈曲分析和二阶弹性分析方法对某既有弧梁钢框架井道的整体稳定问题进行了研究,并分析了弧梁圆弧角大小的影响,得到了一些有益结论,可供同类工程参考。As the improvement of people＇s living standards, the elevator installation engineering for existing buildings is becoming more and more common. For sightseeing elevator hoistway, arcuate beams are often used outside the frame. But the effective length method of China＇s current code ＂code for design of steel structures＂ is not applicable for this steel frame structure with arcuate beam. In this paper, the eigen buckling analysis and second order elastic analysis are applied to structural stability analysis of an existing steel frame hoistway structure with arcuate beam. Then the influence of the areuate angle is analyzed. Some useful conclusions are obtained for reference of similar projects.
