Abstract: Xi′an Maike Business Center project consists of two connected super high-rise tower buildings. The two towers have big difference in structural height and stiffness, and are connected by the truss in high position. The structural system is complicated with irregular planar torsion and vertical members discontinuity, and the building is particularly irregular. The building is the first project in China applied the structural system of concrete filled steel tubular (CFT) column frame, steel concentrically braced core wall and steel connected truss. The structural system and design methods were presented in detail, focusing on the arrangement of the steel concentrically brace, the layout of energy consumption beams and the set of connected structure. Meanwhile the performance-based design methods were described in perspective of the performance requirements of different components in the complex super high-rise steel structure.
Keywords: connected structure; steel concentrically braced core wall; energy consumption beam; performance-based design
