摘　　要：随着建筑日益向高品质方向发展,各种造型新颖的楼梯应运而生。结合启迪设计大厦六折空间曲桥楼梯和四折弹簧空间楼梯等,介绍了异形空间钢楼梯设计在边界条件的确定、结构布置、受力特性、分析方法、构造细节、中间约束和支座设计、舒适度验算等方面与普通楼梯的区别和特点,以及异形钢楼梯荷载试验,可供异形空间钢楼梯结构设计参考。With the increasing development of architecture towards high quality,various uniquely designed staircases have emerged.Combined with the six-fold curved bridge space staircase of Tus-design Building and the four-fold spring space staircase,etc.,the differences and characteristic between of the special-shaped space steel staircase design with the ordinary staircase in the determination of boundary conditions,structural layout,force characteristics,analysis methods,structural details,intermediate constraints and bearing design,comfort evaluation,etc.,as well as the load test of the special-shaped steel staircase were introduced,which can be used as a reference for the design of the special-shaped space steel staircase structure.
