Modelling Concrete Deterioration Effects on Capacity of Marine Wharf Infrastructure
The failure of concrete marine wharves has the potential to cause long-term economic impacts for communities that depend on port infrastructure for trade (example - Kobe, Japan). Considering the aging infrastructure in the US, the piles that support these wharf structures are susceptible to extended degradation from both chloride ingress and carbonation. This study investigates the effects of chloride corrosion on the lateral force capacity and ductility of a wharf-supporting prestressed concrete marine pile, through a probabilistic deterioration model and finite element structural model.
Coastal Flood Risk Assessment for Two Communities in the Bay Area
Through Stanford's Sustainable Urban Systems program's collaboration with Resilient by Design, our team assessed the coastal flood risk to buildings in Burlingame and San Mateo, CA. This assessment was semi-probabilistic, including three sea level rise scenarios and three flooding events. We also mapped the spatial overlap of direct economic losses with specific demographics prevalent in the South Bay.
Note: This work was an exploratory study, in order to find potential regions to further refine our method to quantify potential direct economic losses and cascading impacts in subsequent quarters.
