Abstract:
When designers conceptualize a reinforced concrete sea structure, they need to fully consider the construction methods for reinforcement details. Several prefabrication systems are cited that give excellent uniform behavior. Detail considerations and suggestions are given based on long-term observation of test beams placed in severe tidal exposure in Maine. A unique system of protecting post-tensioning tendons, where small concrete cover is used, is also described.
