Title: City-scale Seismic Resilience of Building Portfolios: Monitoring, Rating, Simulating and Assessment
Abstract:
This presentation presents a methodological framework for city-scale seismic resilience assessment of building portfolios, structured around four interconnected components: satellite monitoring, image-based rating, portfolio simulation, and resilience assessment. The proposed approach first integrates satellite-based remote sensing techniques for rapid post-earthquake damage screening across large building inventories. Building damage states are then quantified through an image-based rating system that enables consistent and scalable condition assessment. A portfolio-level simulation framework is subsequently developed to model the spatiotemporal propagation of seismic damage and the resulting functionality loss across the urban building stock. Finally, a probabilistic resilience assessment method is established to quantify system-level performance, capturing initial damage and post-event recovery trajectories. Together, these components form a coherent “monitoring–rating–simulating–assessment” chain, providing a scalable and data-driven foundation for city-scale seismic resilience evaluation.
