In this paper, a suspended super high-rise building system is proposed, in which the core tube is used as the load-bearing and lateral force-resisting member of each suspension substructure. There are several suspension substructures distributed along the height. The suspension substructures swing in the earthquake, and the phase of each substructure will be different, which artificially forms a “snake dance” mechanism, thus avoiding excessive overturning moment. The dynamics of the suspended super high-rise building is first formulated for both core tube and suspended substructures. A semi-active control algorithm based on a set of fuzzy rules is introduced. The effectiveness is tested by the numerical MR device model built in MATLAB, while the model for the suspended super high-rise building system is created in OpenSEES. The collaborative simulation between MATLAB and OpenSEES is used to simulate the semi-active control on the suspended super high-rise building system. According to the result, the phases of suspended substructures are different, and the overturning moment and the displacement of the suspended substructures decrease significantly compared with the uncontrolled case.
