Overview of Current Prestressing Technology in Offshore Structures
Abstract
This report presents a review of the current design practice in offshore prestressed concrete structures. Major topics include recent applications of prestressing technology in offshore concrete gravity-based structures, current design criteria, and durability design requirements. An appendix summarizes recommendations for further research that is needed to effectively apply prestressing technology to inland waterway navigation structures. Conclusions regarding prestressing technology are that it has gained wide acceptance due to its benefits in the areas of contractibility, durability, and overall economy. If properly designed and constructed, prestressed concrete has proven to enhance the strength and serviceability of offshore structures, especially with regard to shear resistance, fatigue resistance, crack control, and watertightness. The majority of prestressed concrete offshore structures have exhibited remarkably sound and reliable behavior in hostile marine environments.
