Abstract: Changsha Jinmao Meixi Building has 62 floors above ground and 4 floors underground, with a building height of 318m. Changsha Jinmao Meixi Building adopts hybrid strcuture system with steel reinforced concrete column+steel beam+reinforcement concrete core tube+belt truss. The structural system characteristics of the project, the analysis and strategy for out-of-code structure, overall calculation analysis, construction simulation analysis, and elastic-plastic time-history analysis under rare earthquakes were systematically introduced. The analysis results show that the structure has excellent seismic performance to achieve the desired performance goals.  

Keywords:Changsha Jinmao Meixi building； out-of-code high-rise building； hybrid structure； body-shaped retraction； belt truss； construction simulation
