  • Numerical simulation of mechanically stabilized earth walls for parametric evaluation of behavior under surcharge loading

    Creator:
    Ambauen, Spencer J.
    Abstract:
    A numerical model, simulating the complex behavior of reinforced soil walls using the finite element method, was developed to evaluate the behavior of a surcharged, geosynthetic-reinforced retaining wall with modular block facing. A nonlinear elastic-plastic constitutive soil material model was calibrated to experimental plane strain test data, while the performance...

  • Knowing Concepts in the Social and Material Context of Engineering Practice

    Creator:
    Bornasal, Floraliza
    Abstract:
    It is expected that information taught in the context of school will ultimately transfer to workplace settings. To support this transition, educators and researchers advocate for organizing foundational ideas, or concepts, in specific domains of knowing. In the domain of transportation engineering, knowing of concepts, which include "big ideas" such...

  • Bacterial toxicity and metabolism of three hydrazine fuels

    Creator:
    Kane, Donald A.
    Abstract:
    Hydrazine based fuels are used by the Air Force for the Titan II and Minuteman III missiles and the F-16 aircraft and by the National Aeronautics and Space Administration for propulsion systems and the Space Shuttle Program. These uses represent significant production, transportation and storage of these fuels, and, as...

  • Improving Fatigue Cracking and Moisture Resistance of Asphalt Mixtures

    Creator:
    Obaid, Ihsan A.
    Abstract:
    The resistance of asphalt concrete pavement to distresses such as fatigue cracking and permanent deformation is governed by how well the structure can resist loading under a variety of traffic and climate-related conditions. Asphalt binder type and content are typically the variables that pavement engineers can manipulate to render the...

  • Framework for Measuring Construction Project Performance using Energy

    Creator:
    Nnaji, Chukwuma A.
    Abstract:
    Over the years, the performance of construction projects has been a main source of concern given the percentage of a project cost associated with poor project performance. As a result of the growing clamor to improve the output of the built industry, comprehensive studies have been conducted to examine the...

  • Remote Sensing Tools for Evaluating Climate Change Impacts in Coastal Environments

    Creator:
    Herrmann, Joan F.
    Abstract:
    Climate change has pervasive impacts on Earth’s diverse ecosystems. Observed and projected effects that impact coastal environments pose unique challenges. Coastal regions provide numerous ecosystem services (e.g., fisheries, nursery habitats, erosion control, and water filtering and detoxification), house 40% of the US population, and contribute to 58% of the national...

  • Development of an improved system for Oregon to accurately quantify dense-graded hot mix asphalt pavement density

    Creator:
    Darra, Suraj
    Abstract:
    The Oregon Department of Transportation (ODOT) standard specifications require a minimum density for the construction of dense-graded hot mix asphalt (HMA) pavements. Currently, the standard specifications call for density measurements for quality control (QC) and quality assurance (QA) testing to be made using nuclear density gauges that are calibrated using...

  • Chaos in a long rectangular wave channel

    Creator:
    Bowline, Cynthia M.
    Abstract:
    The Melnikov method is applied to a model of parametrically generated cross-waves in a long rectangular channel in order to determine if these cross-waves are chaotic. A great deal of preparation is involved in order to obtain a suitable form for the application of the Melnikov method. The Lagrangian for...

  • Simulation of coastal processes in a circular wave basin

    Creator:
    Katzev, David H.
    Abstract:
    The circular wave basin provides a means of physically modeling the nearshore without the typical problems associated with end walls. Three different coastal processes were examined to demonstrate the use of a spiral wavemaker in a circular wave basin. These were longshore currents, shear waves, and groin circulation. A beach...
