Abstract:
Accidental events that may lead to a progressive collapse (e.g., explosions and collisions) and earthquakes are two types of destructive hazards for super-tall buildings. The study of the resilience of super-tall buildings against these hazards has become a crucial issue. Corresponding research outcomes have important social, political, and economic value for damage/loss assessment and the post-disaster recovery plans for important buildings. A resilient structural system usually exhibits significantly reduced consequences and recovery time after hazards. Therefore, based on the resilience concept and the widely adopted 'frame–truss–core tube' system, a novel seismic–progressive collapse resilient super-tall (SPCRST) building system and the corresponding design method are proposed in this paper. Detailed case study results indicate that, compared with the conventional system, the proposed system has significant advantages in controlling the dynamic responses of super-tall buildings during accidental events and earthquakes (e.g., vertical displacement after local column failure, and floor accelerations and inter-story drifts under earthquakes) and in improving the seismic–progressive collapse resilience of the structure. © 2021 Elsevier Ltd
