Abstract:Reinforced concrete frame-core wall structure is the most commonly used structural system for 150 ~ 250m superhigh-rise buildings. At present, on the basis of conventional rectangular planes and regular vertical elevations, there aremany frame-core wall structures with special shapes. The characteristics of several types of special-shape frame-core wallstructures were summarized, and mainly studies the system research, structural design focus and seismic performanceobjectives of irregular super high-rise buildings, such as buildings with spindle-shaped facades, winding outer framecolumns and large set-back facades. Combined with the structural design of practical over-limit projects, the structuralcontrol indicators and strengthening measures of frame-core wall structures with different special shapes were proposed.

Keywords:special shape; super high-rise building; frame-core wall structure; spindle-shaped facade; winding outer framecolumn; large set-back facade
