  • Shear strengthening reinforced concrete bridge girders using near-surface mounted titanium alloy bars

    Creator:
    Knudtsen, Jonathan
    Abstract:
    Aging and deficient infrastructure has become a major problem throughout the world. This is particularly evident in the case of reinforced concrete (RC) bridges. The cost of replacing these bridges is often prohibitive, thus engineers must find ways to strengthen them. Many older RC bridges predate the modern understanding of...

  • High Strength Reinforcing Bars : Concrete Shear Friction Interface Behavior

    Creator:
    Nielson, Drew R.
    Abstract:
    Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...

  • 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 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...
