Abstract：
A super high-rise building height is 309m and the main tower is 59 layers. It adopts two external hanging and interior climbing tower cranes for vertical transportation. After the main tower sealing its roof and core-tube jacking formwork demolition, one climbing tower crane dismantles the other climbing tower crane, and installing four roof hangs on the roof, the last climbing tower crane and four roof hangs step-by-step dismantles from large to small, the WQ2 roof hang is manual dismantled at last. The structure integral displacement and vertical displacement are less under three conditions for JCD6059 and WQ20 foundation. The maximum deformations difference are 5.1mm and 1.6mm for WQ8 and WQ2 reinforced foundation, it less than L/1000 and meets the deformation requirement.
