Abstract:The east tower building of Kaidaer Hub International Plaza is a hotel building on the top cover of the transportation hub. The the main features of the structure and the related contents of structural  design and analysis were introduced, including the calculation decoupling analysis of the east tower building and podium building, structural system and layout, structural elastic analysis, structural elastic-plastic analysis, structural performance-based seismic design and so on. The results of structural analysis show that the structure achieves the set C-grade seismic performance objective. Detailed structural analysis and demonstration were carried out for the truss spanning the intercity track. The selection of structural system met the building function to the maximum extent, so as to achieve the anticipated economic and safety requirements.

Keywords:Kaidaer Hub International Plaza; performance-based seismic objective; time-history analysis; structural design; frame-shear wall structure; damage of structure member; truss
