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.
