The Xi'an Silk Road Happy World Center Tower project is a special-shaped steel tower,consisting of an inner cylinder steel frame,an outer cylinder mesh shell,a large cantilever hub-and-spoke skirt truss,a top Mobius ring and an outer cylinder shaped ribbon.A construction technology of ultra-high facade large-diameter Mobius ring inner support system was given.The design points of the inner support system,the principle of Mobius ring segmentation,the pre-bias technology of block lifting deformation and the control method of block lifting cumulative deformation were discussed.The technical points in the construction process were analyzed and summarized,which makes up for the shortcomings of similar ring steel structure construction methods,and provides a good reference for the subsequent construction of similar steel structure engineering.
