Abstract:Guanghua Road Campus building of Tsinghua University adopts the tube in tube structural system with high lateral resistance efficiency to achieve the balance between cost control and architectural effect. According to the characteristics of the main structure with high height, the performance-based design method was adopted, the corresponding fortification targets were determined according to the principle of three levels of earthquake resistance, and the corresponding seismic measures were taken. Through elastic, elastic-plastic analysis and design, all indexes of the structure were relatively reasonable, proving that the seismic measures are effective and meet the requirements of the code.

Keywords:super high-rise building; tube in tube structure; performance-based design; seismic measure
