Shear capacity assessment of corrosion-damaged reinforced concrete beams

Creator:: Farrow, William C.
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...

Freeze-thaw durability of reinforced concrete deck girders strengthened for shear with surface-bonded carbon fiber-reinforced polymer

Creator:: Mitchell, Mikal Maxwell
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...

Shear repair methods for conventionally reinforced concrete girders and deep beams

Creator:: Howell, Daniel A.
Abstract:: Many conventionally reinforced concrete deck girder bridges (RCDG) and their intermediate supporting bent caps were designed during the Eisenhower interstate era of the 1950’s with the AASHO design equations at the time, which subsequently place higher demand on the concrete. The referenced components may exhibit diagonal cracking due to the...

Analysis of diagonally cracked conventionally reinforced concrete girders in the service load range

Creator:: Robelo, Melissa J.
Abstract:: Performance evaluation of conventionally reinforced concrete (CRC) bridge superstructure elements with diagonal cracks is of interest to the bridge engineering community. Standardized methods to predict service-level stress magnitudes in cracked bridge girders under combined bending and shear forces are not available. An analysis procedure was developed to determine the response...

Experimental and analytical evaluation of conventionally reinforced deck-girder bridge bent caps with vintage details

Creator:: Senturk, Ahmet Ekin
Abstract:: Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...

Investigation of the fatigue behavior of diagonally-cracked CRC deck-girders repaired with CFRP

Creator:: Williams, Grahme T.
Abstract:: Fiber reinforced polymers (FRP) are becoming more widely used for repair and strengthening of conventionally reinforced concrete (CRC) bridge members. Once installed, the repair may be exposed to millions of load cycles during service life. The anticipated life of FRP repairs for shear strengthening of bridge members under repeated service...

Testing and evaluation of flexural reinforcing bars terminating in columns

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...

Analysis of conventionally reinforced concrete bridge girders for low-cycle fatique in shear

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...

Environmental durability of reinforced concrete deck girders strengthened with surface-bonded carbon fiber-reinforced polymer

Creator:: Sopal, Gautam Jayant
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...

Analysis of conventionally reinforced concrete deck girder bridges for shear

Creator:: Potisuk, Tanarat
Abstract:: Large numbers of 1950's vintage conventionally reinforced concrete (CRC) bridges remain in-service in the national bridge inventory. Many of these bridges are lightly reinforced for shear. Evaluation of these bridges to prevent unnecessary and costly repairs requires refined analytical techniques. This dissertation presents finite element (FE) modeling and comparisons of...
