  • Analysis of thermal fatigue distress of asphalt concrete pavements

    Creator:
    Jackson, N. Mike (Nathaniel Michael)
    Abstract:
    Thermal cracking of asphalt concrete pavements is responsible for millions of dollars in annual maintenance and rehabilitation costs in the United States and Canada. Thermal cracking is typically associated with low temperatures in northern climates and at high elevations. However, another form of thermal cracking, known as thermal fatigue cracking,...

  • The performance of drivers with physical limitations at T-intersections

    Creator:
    Hunter-Zaworski, Katharine M.
    Abstract:
    The research examines the effect of restricted head and neck movement on driving performance as measured by decision time at T-intersections. The traffic safety and human factors literature was reviewed, and very little was found concerning drivers with physical limitations. T-intersections were selected for study because most accidents involving drivers...

  • Indirect parameter identification algorithm in radial coordinates for a porous medium

    Creator:
    Roley, Kenneth L.
    Abstract:
    The decision to bury high level nuclear wastes in deep geological formations led to the study of the Hanford Nuclear Reservation as one of three possible sites for the first nuclear waste repository in the United States. To adequately evaluate the environmental impact of siting nuclear waste repositories in basalt...

  • A linkage finite element for nailed composite wood I-Beams and T-Beams

    Creator:
    Lee, Chyuan-shen
    Abstract:
    With current nonlinear analysis computer capabilities, this study was conducted to develop a linkage element that permits analyses of wood composite structures taking into account possible slip in the nailed joints. The finite elements chosen to represent the wood stud, plywood, gypsum and nails are described. The method as applied...

  • Irregular points in wavemaker boundary value problem

    Creator:
    Tanaka, Yoshihiro
    Abstract:
    A global solution is presented that accurately accounts for the singular behavior at all irregular points. The linearized boundary value problem in a semi-infinite strip in the physical plane is transformed into a smooth unit disk by two successive conformal mappings. The global solution results from a Fredholm integral equation...

  • GOSEP: Georeferenced Oregon Soil Engineering Properties

    Creator:
    Dutille, Victoria L.
    Abstract:
    Geotechnical engineers design and analyze the interface between the natural and built environments, often based on uncertain and inherently variable data due to the nature of the building material, soil. Engineers must estimate the subsurface conditions at a site using historical, in-situ, and laboratory testing data. However, only discrete representative...

  • Mooring analysis of the Ocean Sentinel through field observation and numerical simulation

    Creator:
    Baker, Joshua L.
    Abstract:
    This study presents a mooring analysis of the Ocean Sentinel buoy, which is a mobile test platform for Wave Energy Converters. The Ocean Sentinel is owned and operated by the Northwest National Marine Renewable Energy Center (NNMREC) at Oregon State University (OSU). The study involved a field observation as well...

  • Mass transport in laboratory water wave flumes

    Creator:
    Kim, Tae In
    Abstract:
    A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

  • Numerical Studies on Fluid-Structure Interaction and Applications

    Creator:
    Chen, Ming
    Abstract:
    Fluid-structure interaction (FSI) has been of significant research interest worldwide over the past several decades because of its variety of applications in both offshore and coastal engineering. Researchers analyzing FSI systems rely heavily on experimental tests in model scale in laboratories or large-scale sea trials. However, these tests are often...

  • Experimental behavior of wide-flange beams with web holes

    Creator:
    Horning, Richard Alan
    Abstract:
    Two built-up wide-flange beams with several large holes in each beam were tested to failure. Strains were measured by strain gages at various levels, located at the ends and center of typical holes, and deflections were measured optically at two points on each beam. Lateral bracing was provided to prevent...
