Abstract:Shenzhen Metro Huitong Building is an out-of-code high-rise building. It adopts the dual lateral resistance system of reinforced concrete frame-corewall system with steel reinforced concrete columns adopted in peripheral frame columns in bottom 24 layers. The project′s podium on the west side is a 20m large-span structure, and the podium on the east side has 10m suspension, and inclined columns are set between 7～13 layers of the north side of the tower. The structural system and the overall design indices of the project were briefly introduced and the calculation results of different programs were analyzed and compared. Performance-based design theories were integrated into designs of overall structure and components and the main lateral resistance components met design objectives of not yielding under fortification earthquake, that is, key components keeping elastic under fortification earthquake. The mechanics of W-shaped steel tube column, the vierendeel truss and inclined columns were analyzed in detail, and the dynamic elastic-plastic time-history analysis was carried out on the structure under the rare earthquake. All the indicators of the structure met the requirements of performance-based seismic design and the specifications.

Keywords:super high-rise building; steel reinforced concrete column; performance-based seismic design; dynamic elastic-plastic analysis; buckling analysis; W-shaped steel column
