Highlights PUS key component vulnerability function is proposed for analyzing morphology. A proposed design alleviates brittle damage of PUS large-span structure. Threshold-compliant schemes show strong adaptability to local restorability. Dynamic assessment is an efficient technique to obtain PUS adaptive schemes. The final PUS adaptive scheme prefers a light-asset strategy.
Abstract Prefabricated underground stations (PUS) have become an important aspect of resilient cities. Adaptability to local emergency restoration is a critical target for PUS to achieve resilience after disasters. For this purpose, this study constructed a PUS adaptation resilience assessment framework (PUS-ARAF) with three modules: (1) A PUS key component vulnerability function was proposed to analyze its morphology. (2) A ‘Resilience performance - recovery Time - restoration Cost’ assessment process was established to analyze local emergency restoration. (3) A dynamic assessment was proposed to quickly obtain PUS adaptive schemes for key components. A case study was performed based on the Shenzhen PUS and the results indicated that (1) the Joint-region-weak-link scheme alleviated brittle damage on PUS large-span structures and achieved 0.97 bearing and 0.96 energy absorption capacities of continuous-section beam, (2) local emergency restorability exhibits conditional function characteristics with local factors. Threshold-compliant schemes demonstrate easy adaptation to local restorability at minimal cost. (3) PUS-ARAF developed local adaptive schemes with minimum restoration time and cost, and (4) the final PUS adaptive scheme preferred a light-asset strategy and was applied to the Shenzhen PUS. The PUS-ARAF provides adaptive schemes and local-adaptive life-cycle resilience strategies for PUSs.
