Efficient System Reliability Assessment of Shoreline Seawalls: Applications to SEAHIVE

Seawalls play a critical role in protecting coastal transportation systems, but their performance is deteriorating under increasing structural demands and changing environmental conditions. This project develops a practical framework for assessing the reliability of shoreline seawalls, with a focus on SEAHIVE®, a novel seawall system made of concrete perforated hexagonal prisms deployed in the Miami area. Working in two phases, the team will first evaluate the reliability of individual seawall components using inspection ratings and limit-state analysis, then scale up to system-level reliability by accounting for how deterioration and soil conditions vary across locations. The result will be a decision support tool that helps inspectors and asset managers identify vulnerable sections and prioritize maintenance.
