Abstract: In order to meet the requirements of building facade and usage, Jinqiao Guopei Center adopts a suspensionstructure system. The suspension structure system consists of a core tube, suspension trusses, hanging columns and a floorsystem. Combined with the characteristics of the project, the selection of tower structure and the structural system andlayout of the suspension system were introduced. The viscous damping walls were set in the core tube to reduce the seismiceffect of the main structure, as an effective strengthening measure for the single lateral force structural system. Themechanics performance of the suspension structure was comprehensively analyzed to verify that the overall index of thestructural behavior meet the requirements of the specification. Special analysis was carried out on the key problems of thesuspension structure, including the analysis of the effect of the floor, the analysis of the unfavorable distribution of theactive load, the analysis of the prevention of progressive collapse and the analysis of the floor vibration comfort, etc., toevaluate the reliability of the local structure and propose corresponding strengthening measures. Through the time historyanalysis under rare earthquakes, it is proved that the suspension structure meets the seismic performance requirements.

Keywords: Jinqiao Guopei Center; suspension structure; suspension truss; hanging column; viscous damping wall;prevention of progressive collapse
