Structural design of special-shaped space steel staircase
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.
