Time-Dependent Probabilistic Capacity Assessment of a Prestressed Concrete Pile in a Spatially Varying Corrosive Marine Environment Using Detailed Finite Element Methods

Abstract

This study aims to provide a comprehensive method for modeling and analyzing prestressed concrete substructure elements, specifically wharf piles, subjected to chloride-induced corrosion. Fully understanding this process is crucial to capturing uncertainties in structural response and providing accurate predictions of its time-dependent degradation mechanisms. A probabilistic modeling framework and detailed finite element model and analysis are employed to explore these effects. Results indicate a high degree of uncertainty captured by the spatial and timedependent modeling techniques in addition to stress corrosion cracking and brittle failures modes observed in the finite element analysis.
