Abstract:Combined with the characteristics of super-long cantilever, large hole in facade, discontinuous floor, discontinuity of vertical members, structural transformation, sky steel bridge, large-span stair and the high seismic intensity, the structural system of Tencent(Beijing) Headquarters Building adopts reinforced concrete corewall\|large cantilever mega steel truss-concrete frame. Considering the special structural system, complex shape, serious out-of-code items and the importance of the project, the performance-based seismic design method was adopted. The calculation and analysis were checked by multiple programs. The calculation results were calculated according to multiple models and the enveloping method was adopted, and the detailed design measures were put forward. Due to the particularity of the super-long cantilever structure, detailed analysis was conducted on the vertical earthquake action of the cantilever part, the influence of different construction orders, comfortability, structural floor and key nodes. BIM technology was used to optimize the connection between reinforcing bar and section steel and interspersed relationship between reinforcing bars. The natural raft thick plate foundation and anti-floating small pile scheme were adopted to effectively control the settlement differences of all parts of the foundation, thus meeting the engineering progress requirements.
Keywords:Tencent(Beijing) Headquarters Building; cantilevered structure; floor discontinuity; vertical seismic action; performance-based seismic design; comfortability; construction simulation
