Abstract

Resilience-based seismic design of reinforced concrete (RC) tall buildings has become an important trend in earthquake engineering. Seismic isolation technology is an effective and important method to improve the resiliency of RC frame-core tube tall buildings located in high seismic regions. However, the traditional design method for this type of building does not focus on the key design parameter, namely, the yield ratio of the isolation system and has therefore been proved to be highly inefficient. To address these issues, the rational yield ratio of isolation system for such buildings is investigated based on 28 carefully designed cases, considering the influences of total heights, yield ratios and seismically isolated schemes. The rational range of the yield ratio is recommended to be 2-3%. Based on this, a high-efficiency design method is proposed for seismically isolated RC frame-core tube tall buildings. Subsequently, a seismically isolated RC frame-core tube tall building with a height of 84.1 m is designed using the proposed design method. The rationality, reliability and efficiency of the proposed method are validated. The research outcome can serve as a reference for further development of the seismic design method for seismically isolated RC frame-core tube tall buildings. View Full-Text
