  • 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,...

  • 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...

  • Aseismic performance of a cable-stayed structure with decentralized H[infinity] control

    Creator:
    Chńg, Guan B.
    Abstract:
    The dissertation uses state-of-the-art structural engineering theories, in parallel with the modern and still-developing control theory of electrical engineering to mitigate the vibratory responses of a double-stayed bridge subjected to strong earthquake ground motions. First, a nonlinear finite element model of the double-stayed bridge subjected to non-uniform (multi-support) earthquake excitations...

  • In situ measurement of the benthal oxygen requirements of tidal flat deposits

    Creator:
    Crook, Gene Ray
    Abstract:
    In situ light and dark planktonic and benthal respirometers were used to measure the oxygen requirements of Yaquina estuary water and benthal deposits. Respirometer devices were constructed so that actual conditions of mixing could be simulated and benthal deposit disturbance would be minimized. A mathematical model of a benthal respirometer...

  • Spatial, diel and seasonal variations in dissolved oxygen and temperature within a stratified lake

    Creator:
    Smith, Stanley Allan
    Abstract:
    Spatial, diel and seasonal variations in dissolved oxygen and temperature were measured in Triangle Lake, Oregon. Spatial dissolved oxygen and temperature variations measured in the stratified lake are presented to illustrate the horizontal uniformity of the lake and to demonstrate the applicability of the one dimensional assumption for sampling and...

  • Bond strength investigations and structural applicability of composite fiber-reinforced polymer (FRP) rebars

    Creator:
    Kachlakev, Damian I.
    Abstract:
    The composite FRP rebars research at Oregon State University was initiated in 1993 principally to develop a non-metallic hollow reinforcement. It was recognized that the tensile properties of such reinforcement are unquestionably superior to steel, but its performance in concrete could be problematic. The bond between FRP rebars and concrete...
