Abstract:
Deterioration and necking of J-bars has been reportedly observed at the interface of the footing and stem wall during the demolition

of older retaining walls and bridge abutments. Similar deterioration has been reportedly observed between the pier column and

footing. Any decrease in the area of steel at these interfaces may result in foundation instability, and hamper efforts to rehabilitate

or preserve existing foundations.

The objective of this project is to determine the extent and nature of deterioration and/or necking of J-bars in existing bridge

structures. This must be understood in order to identify existing structures having the potential for or existence of deteriorated Jbars.

Once at-risk structures are identified, methods to identify and validate deterioration and remedial measures, details, and

methodologies are developed to address affected structures.
