Abstract: Shaanxi Yinlong Building project consists of two high-rise buildings with completely different building shapes andstructural heights and connected by a corridor at high position, which forms twin-tower connected structure. The structuralsystem is complex, the plane torsion is irregular and the vertical members are discontinuous, which is particularly irregularbuilding. The two towers use steel frame-eccentric support core tube and steel frame-support structure system respectively.The structural system and design methods were introduced in detail,including the arrangement of steel eccentric supports,the arrangement of energy dissipated link beam, and the arrangement of the connecting body structure, etc. Many softwaresuch as YJK, MIDAS / Gen, ETABS, PERFORM-3D etc. were used to check the bearing capacity and deformation capacityof structural members under frequent earthquakes, fortified earthquakes, and rare earthquakes, and the check calculationresults meet the requirements of relevant codes. Meanwhile the performance-based design methods were described inperspective of the performance requirements of different components in the complex super high-rise steel structure.

Keywords:Shaanxi Yinlong Building; connected structure at high position; steel eccentric support core tube; energydissipated link beam; performance-based design
