Abstract:Wuhan MIXC Residential Building 5# with 174.15m height is a high-rise building beyond B-level height，and the partial frame-support shear wall system is used. The shear wall multi-tube structural system is used for main structure that above the transfer storey, which can solve the problem of insufficient lateral stiffness of structure with large height-to-width ratio and effectively controls the maximum thickness of the shear wall. The principles and methods of performance-based seismic design, the foundation design, the overall elasticity calculation results, the dynamic elastic-plastic analysis results under rare earthquake were introduced. In addition, several key problems were deeply discussed, such as the layout of shear wall multi-tube structure, model simplification of accentual transfer beam, the design and analysis of transfer member, which verifies the rationality and safety of the design.

Keywords:super high-rise building;frame-support conversion structure;large height-to-width ratio;shear wall multi-tube structure;performance-based seismic design
