  • 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...

  • Bridge Damage State Detection Based on Strain-Based Wireless Structural Health Monitoring

    Creator:
    Slaven, Kelli R.
    Abstract:
    The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges...

  • 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,...
