Abstract: Tube-frame structural system with outriggers is adopted in super high-rise building Wuhan Center Tower. Huge size concrete filled steel tubes（CFT）act as columns and steel-concrete composite shear walls are used at the bottom part of the tube structure. Structural characteristics of the project were expatiated, and seismic measures for this structure that is beyond the scope of Chinese code were introduced. Details of the huge size CFT column and the column-beam joint, as well as different approaches of outrigger-tube connection were explored. Method of adjusting force distribution by optimizing the construction process with active control technology was attempted.

Keywords:  concrete filled steel tube; outrigger; steel-concrete composite shear wall; structural force；active control
