| 摘 要： | 本螺旋楼梯为某五星级酒店的门户楼梯,楼梯内径1.05m、外径3.45m,计算旋转角度为360度,采用钢结构。本文通过不同的计算模型分析了钢螺旋楼梯的空间受力性能,并将分析结果用于实际工程的设计指导。钢螺旋楼梯的空间受力性能主要表现为:支承于内弧梁的横梁同时对外弧梁提供支承作用,使内外弧梁的变形趋于协调。

| Abstract: | The spiral stairs is a five-star hotel portal stairs.The inner and outer diameters of the stairs are respectively 1.05m and 3.45m.The calculated rotation angle is 360 degrees,with steel structure.Through the different calculation models,this paper analyzes the space mechanical behavior of the steel spiral stairs,and the analysis results are used to guide the design of the actual engineering.The space mechanical behavior of the steel spiral stairs is mainly as follows: the crossbeams,supported on the inner arc beam,also support the outer arc beam,the deformation of inner and outer arc beam tends to coordination. |
