Rapid Repair of Column to Footing Phase 2

The objective of Phase 2 of this research would be to explore additional configurations and further develop the plastic hinge relocation repair method investigated in Phase 1. The final product would be to append and update the existing design guide to include recommendations for the parameters considered. Rapid post-earthquake repair by plastic hinge relocation has been shown to be effective based on work conducted at NC State. A simple technique has been developed, however, additional variations are possible which may be suitable under varying conditions of damage. The Phase 2 column to footing tests proposed here will leverage the remaining columns that are already damaged and ready for repair. The columns would otherwise be disposed. The techniques proposed as part of this work would add to the rapid repair techniques already developed and also build confidence in the capability of the repair itself. This could provide valuable information to decision makers when considering the options and potential consequences when planning for such an event.
