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...

Creator:: Keshari, Shweta
Abstract:: This thesis is the consequence of a research effort undertaken by the School of Civil and Construction Engineering at Oregon State University and funded by the Oregon Department of Transportation (ODOT) and the Federal Highway Administration (FHWA). The principal objective of the effort was to reduce the life cycle cost...

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,...

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...

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...

Creator:: Smith, Matthew T. (Matthew Todd)
Abstract:: Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...

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...

Creator:: Chansawat, Kasidit
Abstract:: The Horsetail Creek (HC) bridge is an example of an Oregon bridge that was classified as structurally deficient and was not designed to withstand earthquake (EQ) excitations. A fiber-reinforced polymer (FRP) rehabilitation was performed on the HC bridge to increase flexural and shear capacities for traffic loads. However, a seismic...
