Shear capacity assessment of corrosion-damaged reinforced concrete beams
The research presented here is a study to determine the effect of shear reinforcement corrosion on the shear capacity in conventionally reinforced concrete (CRC) bridge elements. A total of 14 CRC beams were tested using three stirrup spacings (8, 10, and 12-inch). Six of the beams included the infl...

| Summary: | The research presented here is a study to determine the effect of shear
reinforcement corrosion on the shear capacity in conventionally reinforced
concrete (CRC) bridge elements. A total of 14 CRC beams were tested using
three stirrup spacings (8, 10, and 12-inch). Six of the beams included the
influence of a 4-inch thick deck, and both positive and negative moment
regions were considered. The CRC beams were subjected to an accelerated
corrosion process to produce the damage states. Inspection techniques were
used to visually correlate corrosion damage with actual structural performance.
Severe corrosion damage was shown to have significant effect on the shear
performance of the CRC beams. Findings indicate that current inspection
ratings for corrosion damage may not adequately identify the extent of
structural deterioration. === Graduation date: 2003 |
