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.
