  • 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...

  • Stochastic Characterization of Highway Capacity and Its Applications

    Creator:
    Dong, Shangjia
    Abstract:
    Highway capacity has traditionally been treated as deterministic. In reality, however, capacity can vary from time to time and location to location due to inclement weather, various driving behavior, traffic incident, bottleneck and workzone. This thesis aims to characterize the stochastic variations of highway capacity, and explore its applications. The...

  • Hydrodynamic contact/impact modeling and application to ocean engineering problems

    Creator:
    Challa, Ravi
    Abstract:
    Fluid-structure interaction (FSI) is a very interesting and challenging multi-disciplinary field involving interaction of a movable or deformable structure with an internal or surrounding fluid flow. FSI has several practical engineering applications such as the determination of the hydrodynamic forces on a structure or the dynamics of motion of bodies...

  • Ultimate and serviceability limit state reliability-based axial capacity of deep foundations

    Creator:
    Reddy, Seth C.
    Abstract:
    Deep foundations are necessary for the construction of many structures, such as bridges and buildings, located in areas unsuitable for shallow foundations. Owing to the inherent variability of soil and the complex changes that occur in the soil adjacent to deep foundations as they are installed, the ability to accurately...

  • Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

    Creator:
    Mustafa, Nizar Ahmad
    Abstract:
    Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...

  • An analysis of wave forces on prototype walls under tsunami loading

    Creator:
    Oshnack, Mary Elizabeth
    Abstract:
    This thesis is comprised of two manuscripts based on a laboratory experiment conducted to examine realistic wave forcing on a vertical wall subjected to tsunami loading. The first manuscript examined tsunami force and pressure distributions on a rigid wall that was fronted by a small seawall. Six different seawall heights...

  • EMD based hybrid models in short term traffic speed forecast

    Creator:
    Liu, Lu
    Abstract:
    Short-term freeway traffic speed prediction is essential to improving mobility and safety. It has been a challenging, yet unresolved issue. Traffic speed prediction can be applied to enhance the intelligent freeway traffic management and control for applications as operational and regulation planning. For example, with more reliable traffic speed prediction,...

  • Development of an ACIP pile-specific load-displacement model

    Creator:
    Adami, Nasim
    Abstract:
    Augered cast-in-place piles, also known as ACIP piles, have been used for more than seven decades in the United States and have gained in popularity due to their relatively quick installation and cost-effectiveness. Owing to the reduced impact on the neighboring environment as compared to some other deep foundation installation...

  • Assimilation of Multi-Sensor Data into Numerical Hydrodynamic Models of Inland Water Bodies

    Creator:
    Javaheri, Amir
    Abstract:
    Numerical models are effective tools for simulating complex physical processes such as hydrodynamic and water quality processes in aquatic systems. The accuracy of the model is dependent on multiple model parameters and variables that need to be calibrated and regularly updated to reproduce changing aquatic conditions accurately. Multi-sensor water temperature...

  • Probabilistic Tsunami Hazard and Damage Assessment of the Built Environment : Applied at Seaside, Oregon

    Creator:
    Park, Hyoungsu
    Abstract:
    Damage estimates to the built environment from tsunamis are important for disaster mitigation, including planning emergency response and recovery. This dissertation evaluates the damage states of buildings in a small urban coastal city, Seaside, Oregon, from tsunami hazards generated by a Cascadia Subduction Zone (CSZ) event. This study is separated...
