Abstract:Xiang Jiang Fortune Financial Center comprises two out-of-code high-rise buildings, of which T1 Tower has structure height of 324m, and T2 tower of 255m. In order to achieve the facade effect of architectural design, a huge oblique crossing lattice is needed to form by the outer frame of the structure, and the facade effect of the building design can be achieved by combining the change of the curtain wall. Combined with architectural features, the structural design adopts complex multiple lateral force resisting structural system. The elastic analysis and elastic-plastic analysis, the structural performance-based seismic design, stability analysis of outer framed columns and finite element analysis on key node were conducted on the whole structure according to multiple calculation programs. The main structure can meet the performance requirements of fortification goal, and the structural system has effective energy dissipation mechanism and good seismic performance.

Keywords:super high-rise building; huge oblique crossing lattice; multiple lateral force resisting; performance based seismic design; stability analysis
