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...

Design, analysis and evaluation of bridge superstructures for live loads

Creator:: Turan, O. Tugrul
Abstract:: Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...

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...

Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

Creator:: Johnson, Brandon Ang
Abstract:: Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...

High-cycle fatigue response of diagonally-cracked conventionally reinforced concrete bridge girders

Creator:: Lee, Ae-young S.
Abstract:: The behavior of stirrups engaged by diagonal cracks and under service loads is largely unknown. Full-size laboratory specimens were loaded to induce diagonal cracks and subjected to high-cycle fatigue loading to represent a service life of 50 years. Tests indicated little change in the average stirrup stress range and mean...

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...

A torsional investigation of a concrete I grider

Creator:: Martin, Roy Charles
Abstract:: This paper investigates a particular bridge construction technique which could result in a significant torsional moment. The structural member under consideration is a prestressed concrete girder for which no torsional consideration is made. Torsional shear stresses can be adequately approximated for an I-shaped girder. Laboratory model tests were performed to...

Laboratory performance of highway bridge girder anchorages under hurricane induced wave loading

Creator:: Lehrman, Jora
Abstract:: Many bridges along the Gulf Coast of the United States were damaged by recent hurricanes, and many more are susceptible to similar damage. This research examines performance of common anchorage connection details for AASHTO Type III prestressed concrete girders used by some transportation agencies. Full-scale specimens were fabricated and tested...

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...
