Abstract: The structure height of A1# building in Jiujiang International Financial Plaza is 299.3m, which adopts the steel reinforced concrete (steel) frame-core tube hybrid structure system. The engineering characteristics and structural analysis of A1# building were introduced. PKPM-SATWE software was used to perform elastic analysis under frequent earthquakes, and Perform 3D software was used to perform dynamic elastoplastic time history analysis under rare earthquakes. The results show that the structure can meet the set seismic performance target. The performance-based design method was adopted for the structural out-of-limit situation, and the ring-belt truss design method was discussed to provide some reference for the design of the same type of super high-rise buildings. 

Keywords:super high-rise building； hybrid structure； seismic performance design； dynamic elastoplastic time history analysis
