摘　　要：文中对某办公楼的不规则折返式钢结构盘梯的受力进行了研究,提供了钢结构盘梯的一种结构体系及其主要受力构件U字形钢板梯梁的做法。采用SAP2000对该不规则钢结构盘楼进行有限元分析,找出了不规则钢结构盘梯的梯梁和踏步板受力最不利位置和变形最大的位置。研究发现,不规则钢结构盘的梯段支座处、梯段的转角弯折处为受力较大区域,应采用构造措施进行加强,同时也给出了加强方法和构造设计大样。In this paper,the stress of irregular returnable steel ladder in an office building is studied,and a structural system of steel ladder and the method of U-shaped steel ladder beam as the main stress member are provided.In this paper,the finite element analysis of the irregular steel structure is carried out by SAP2000,and the most unfavorable position and deformation position of the ladder beam and step plate of the irregular steel structure are found out.Through the research,it is found that the support of the ladder section and the corner bend of the ladder section of the irregular steel structure plate are the areas with large forces and should be strengthened by structural measures.
