Experimental investigation of repaired reinforced concrete highway bridge columns

The following report is a pilot study intended to determine the effectiveness of repaired reinforced concrete highway bridge columns. Four scaled down columns were designed, built and tested to determine behavior and ultimate strength. Each specimen had a different configuration corresponding to various stages of deterioration and repair. Data recorded consists of axial deflection and concrete strain along with axial load. Comparisons of the specimens were made to determine the differences in behavior and ultimate strength. Results have indicated strength is fully restored, however it is recommended further study be conducted for a stronger verification.
