Abstract:Based on the structural design of a 300-meter super high-rise tower with a thin core tube in Nanning，a few unconventional practices were introduced，including the design of the composite foundation with variable stiffness, the application of steel tube confined high strength concrete shear wall, the check of rigidity-to-gravity ratio and shear-to-gravity ratio, the analysis of setting outrigger truss, the later connection outrigger truss node that considering the effect of concrete creep etc， which could provide reference for future design of the similar structures.

Keywords:high-rise building; composite foundation; steel tube confined high strength concrete shear wall; outrigger truss; concrete creep
