Abstract
With the increasing application of spiral steel staircases in practical engineering,the growing diversity of structural configurations has imposed higher demands on design selec-tion.Taking an indoor spiral steel staircase in a newly constructed office building as an ex-ample,the finite element model was established using Midas Gen software.Through strength,deformation,and comfort assessments,three common structural layout schemes for rotating staircases were compared and evaluated from six aspects:Mechanical character-istics,deformation coordination capability,overall stiffness,comfort performance,steel us-age,and construction convenience.Based on different application scenarios and performance requirements,the study proposes recommended structural configurations to provide valuable reference for design selection in similar engineering projects.关键词
