Abstract:Combined with the characteristics of the building, the structural design of a 300m high super high-rise office tower building was mainly introduced. It adopted the concrete frame-core wall structural system. The outer frame columns of the high-position zone of the tower building were all inclined columns, and the facade effect of the architectural design was achieved by combining the curtain wall change. The elastic and elastic-plastic analysis, the performance-based seismic design and the stability analysis of the frame column were carried out by using various calculation programs. The results show that the main structure can meet the performance objectives, and the structural system has an effective energy dissipation mechanism and good seismic performance.

Keywords:super high-rise building; frame-corewall structure; performance-based seismic design; stability analysis
