  • Multi-hazard Damage and Loss Assessment of Bridge Networks

    Creator:
    Burns, Patrick O.
    Abstract:
    The overarching objective of this study is to examine and compare the vulnerabilities of bridges combining effects of earthquake-induced ground shaking, ground failure (e.g., landslides and lateral spreading), and tsunami inundation. A parametric study is performed to understand the sensitivity of economic loss and traffic capacity with respect to the...

  • The Effects of Temperature on Electrical Resistivity Measurements of Concrete

    Creator:
    Coyle, Alex T.
    Abstract:
    Measuring resistivity as a method to calculate formation factor is becoming a popular way to evaluate transport properties of concrete. Resistivity measurements are dependent on multiple factors including the resistivity of the pore solution, leaching effects, the degree of saturation of the specimen, the age of the specimen (degree of...

  • Mapping Nearshore Bathymetry with Spaceborne Data Fusion and State Space Modeling

    Creator:
    Forfinski-Sarkozi, Nicholas A.
    Abstract:
    Despite numerous techniques for measuring and estimating water depth, bathymetry in the nearshore zone is notoriously difficult to map. Dangerous sea states, noisy environmental conditions, and expensive survey operations, particularly in remote areas, contribute to the difficulties of obtaining data along the coast. Global datasets, derived mainly from satellite altimetry...

  • 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...

  • Accuracy assessment of LiDAR point cloud geo-referencing

    Creator:
    Williams, Keith E.
    Abstract:
    Three-dimensional laser scanning has revolutionized spatial data acquisition and can be completed from a variety of platforms including airborne (ALS), mobile (MLS), and static terrestrial (TLS) laser scanning. MLS is a rapidly evolving technology that provides increases in efficiency and safety over static TLS, while still providing similar levels of...

  • A validation of the Oregon State University driving simulator

    Creator:
    Brown, Lacy S.
    Abstract:
    Driving simulation is widely accepted as a safe, effective, and economical alternative for investigating driver behavior in a variety of contexts. However, in order to apply simulator-based research results to real-world settings, the performance measures acquired through simulated driving experiments must first be validated. This research was aimed at validating...

  • Height Modernization from Static GPS Networks in Oregon: Evaluating NGS Guidelines and OPUS-Projects

    Creator:
    Kerr, Darren J.
    Abstract:
    Determining accurate elevations is important for many engineering and scientific applications, and finding these heights via GNSS increases efficiency and significantly reduces the costs as compared to precise geodetic leveling. The National Geodetic Survey (NGS) has published guidelines for determining both ellipsoidal and orthometric heights with GPS to within 2...

  • Wave-current interaction induced by standing long waves in the surf zone

    Creator:
    Phaksopa, Jitraporn
    Abstract:
    This dissertation has focused on the charateristics of bubbles generated by breaking waves and the feedback of wave-current interaction on the forcing mechanism of low frequency wave especially basin seiching wave. For the first study, Optical image capture observations of breaking waves in a laboratory surf zone are presented. The...

  • Fluid-structure interaction analysis with the particle finite element method

    Creator:
    Zhu, Minjie
    Abstract:
    To facilitate the evaluation and design of structures subjected to fluid loading, a study of fluid-structure interaction (FSI) using the particle finite element method (PFEM) is presented to approximate the responses and sensitivities of structures which interact with fluid. A wide range of structural types are permissible by making no...

  • Examination of lateral stiffness and strength of pitched residential roof diaphragms with implications for seismic design.

    Creator:
    Kirkham, William J.
    Abstract:
    There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...
