Although earthquake-induced collapse analysis is one of the most efficient methods to quantify the collapse resistance of buildings, little research has been reported on using the collapse analysis to evaluate the seismic safety of super-tall buildings during the design stage. To optimize the design taking into account earthquake-induced collapses, a real world super-tall building with a height of greater than 500 m is investigated in this work. Throughout its design procedure, earthquake-induced collapse analyses are performed to optimize the design at three different levels (the structural system level, design parameter level and component level). At the structural system level, the influence of different lateral force resisting systems on the collapse resistance is discussed; at the design parameter level, the influence of minimum base shear force is discussed; and at the component level, the influence of high-performance shear wall on the collapse resistance is studied. Based on these discussions, the optimal design scheme of the building is established to improve the seismic safety while maintaining the cost of construction. Given more and more super-tall buildings will be constructed with new structural system and components, this work will provide important references for the seismic design of super-tall buildings and the corresponding collapse resistance research in the future.
