  • Quantification of landslide movement in a forested environment

    Creator:
    Conner, Jeremy C.
    Abstract:
    Landslides are an insidious natural hazard, which can result in significant damage to public infrastructure. Limited monitoring tools are available, particularly tools suitable for use in forested environments. These tools often only allow a few locations across the slide to be monitored. Terrestrial Laser Scanning (TLS) shows promise as a...

  • Contact time and reaction rates for trickling filters

    Creator:
    Roach, Michael Dan
    Abstract:
    Three deep experimental filters were used to evaluate the influence of the physical factors of media size, depth of filter, and organic and hydraulic loading on contact time and the rate of removal of organic material by the biological growth on the filters. A further correlation was made between contact...

  • An investigation of Oregon weight-in-motion data for bridge rating implementation and evaluation

    Creator:
    Pelphrey, Jordan Michael
    Abstract:
    The LRFR Manual, within commentary Article C6.4.4.2.3, contains provisions for development of site-specific live load factors. In Oregon, truck Weigh-in-Motion (WIM) data were used to develop live load factors for use on state-owned bridges. The factors were calibrated using the same statistical methods that were used in the original development...

  • 3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

    Creator:
    Scoggins, Luke A.
    Abstract:
    A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

  • Tsunami Simulation Using OpenSees : Validation of Bridge Response and Exploration of Shallow Water Flow

    Creator:
    Cressman, Luke R.
    Abstract:
    The finite element software framework, OpenSees, has been used by researchers to simulate the response of structural and geotechnical systems to earthquake loading. Implementation of the Particle Finite Element Method (PFEM) has made it possible to simulate hydrodynamic forces through fluid-structure interaction (FSI) in OpenSees. To validate the FSI implementation...

  • Influence of Uncertainties in Terrestrial Laser Scanning on Structural Reliability and Bridge Load Rating

    Creator:
    Loving, Carly K.
    Abstract:
    To ensure the safety of the nation’s bridges, the National Bridge Inspection Standards (NBIS) require all bridges to undergo routine load rating analyses to assess their structural capacity. Accurate geometric information for each structure is necessary for load rating analyses. This information is typically ascertained from as-built plans. Still, when...

  • Finite element modeling of reinforced concrete bridge columns with steel jackets using plastic hinge integration

    Creator:
    Carlton, Adam K.
    Abstract:
    In recent years confinement requirements for concrete columns have increased in seismic regions. Steel jackets are one way to confine reinforced concrete columns. The increased confinement provides additional strength and ductility for the columns during seismic events. For reinforced concrete columns with steel jackets, there are different section properties in...

  • Performance of wood frame wall with thin shell ECC shear panel

    Creator:
    Lewis, Michael C.
    Abstract:
    The overall goal of this study was to evaluate an alternative to traditional wood framed shear wall construction. This study introduced the innovative idea of using a water and seismic damage resistant, wood-concrete- composite (WCC) construction instead of an all-wood design. The WCC design consisted of a thin shell of...

  • Bridge Model Parameter Sensitivity in Pushover and Nonlinear Time History Analysis

    Creator:
    Johnsohn, Karryn E.
    Abstract:
    The aim of this research is to understand and quantify the modeling differences between CSiBridge and OpenSees, and to determine sensitive model parameters. When designing bridges for the high seismic region of California, the California Department of Transportation (Caltrans) performs nonlinear time history analysis of their bridge models. For three-dimensional...

  • Finite element modeling of gusset plate failure using OpenSees

    Creator:
    Walker, Andrew J.
    Abstract:
    The collapse of the I-35W Bridge in Minneapolis, MN in 2007 prompted an investigation into the design and inspection of the steel truss bridges. Further investigation into the collapse revealed that a gusset plate experienced sway buckling, causing the bridge failure. This bridge failure motivated research into the analysis and...
