Abstract:: 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...

Creator:: Koester, Carl C.
Abstract:: Capacity of transverse 1950's vintage reinforced concrete deck girder bridge bent caps with large straight bar anchorages were investigated and evaluated. Eleven subassemblage column specimens were examined with different anchorage lengths, bar groupings, amount of transverse steel, and externally applied axial force. Test results showed an increase in anchorage capacity...

Creator:: Forrest, Richard W. B.
Abstract:: Increasing load magnitudes and loss of reinforcing steel cross-sectional area from corrosion creates the potential for low-cycle fatigue (LCF) in conventionally reinforced concrete (CRC) bridge girders lightly reinforced for shear. LCF of reinforcing steel may be of particular concern. Little data are available for LCF of reinforcing steel without stress...

Abstract:: Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) U-wraps for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged freeze-thaw cycling. CFRP...

Abstract:: Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged environmental exposure and combined...

Creator:: Dawson, Matthew Ryan
Abstract:: Current ACI design provisions for shear in reinforced concrete (RC) beams strengthened with externally bonded carbon fiber-reinforced polymer (CFRP) U-wraps may not adequately account for the effect of scale. This paper describes tests of 6 geometrically scaled beams to identify possible scale effects of such beams. Results indicated that effective...

Creator:: Daniels, Theresa Kathryn
Abstract:: Assessment of an existing bridge is needed when the structure exhibits signs of distress. Assessment practices require refinement in the calculation of loading and resistance while maintaining an acceptable level of risk, to minimize costs associated with repair, replacement and weight restrictions. Previous risk-based assessments evaluated the strength cases for...
