description: Many reinforced concrete structures are deficient in stiffness, ductility, and strength capacity compared to current standards. When a powerful event, such as an earthquake, occurs, un-strengthened, and inadequate concrete members may fail and produce catastrophic results. To counteract this problem, many different retrofit and repair methods have been studied, implemented, and have produced a variety of results. This research is focused on comparing dozens of retrofit and repair methods for reinforced concrete columns to analyze the efficacy of these methods. The primary methods compared are reinforced concrete jacketing and a variety of steel confinement methods. The steel confinement methods include steel jackets, steel cages, precambered steel plates, and pre-stressed steel sections. Varieties of constraints are compared across the methods including the loading, interface mechanisms, connection methods, size, and orientation of the jacket. Each retrofit method functions differently under each constraint, and the benefits and downsides of each were discussed and compared.
