  • A Numerical Investigation of the Bearing Capacity of Shallow Foundations on Salt-Encrusted Flat Sabkha

    Creator:
    Refaei, Raied
    Abstract:
    Salt-encrusted flats, or Sabkha, are common in arid and semi-arid regions worldwide, including coastal and inland areas. Due to their low shear strength and high compressibility, these soils are often unsuitable for supporting infrastructure or structures. The unique salt content of sabkha formations sets them apart from other soil types....

  • Behavioral thresholds in mixtures of sand and clay

    Creator:
    Simpson, Daniel Corder
    Abstract:
    Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced (and in some cases, governed) by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

  • Unsaturated Soils and Foundation Design : Theoretical Considerations for an Effective Stress Framework

    Creator:
    Baker, Josiah D.
    Abstract:
    This study presents the theoretical background necessary to model the bearing capacity of shallow and deep foundations in partially saturated soils. The conventional bearing capacity equations for shallow and deep foundations and the 𝛽-method for deep foundation side resistance have been modified to include the effects of matric suction and...

  • Engineering Behavior of Remolded Diatomaceous Silts

    Creator:
    Pitso, Talenta
    Abstract:
    Diatomaceous soils are a geological material whose engineering properties do not readily conform to the widely accepted and used mechanical and behavioral frameworks. This ambiguity results in design difficulties and geotechnical failures which can be costly. Diatomaceous soils have diatoms in their matrix. Diatoms are unicellular algae with an inert...

  • Characterization of the Small-Strain Stiffness of Soils at an In-situ Liquefaction Test Site

    Creator:
    Donaldson, Aleyna M.
    Abstract:
    Strong ground motions from earthquakes can result in the reduction of the shear modulus and wave propagation characteristics of soils, and can produce liquefaction and cyclic softening during shaking and for some time following the seismic event. While the ground motions produced from controlled blasting are different than those in...

  • 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...

  • Comparison and Validation of Hydrodynamic Theories for Wave Energy Converter Modelling

    Creator:
    Leary, Matthew M.
    Abstract:
    A wide variety of hydrodynamic theories are utilized to approximate a Wave Energy Converter’s (WEC) equation of motion. Numerous theories have been refined in order to improve numerical approximations of WEC dynamics. When incorporating refined hydrodynamic theories into numerical models, there are distinct impacts on WEC rigid body motions, cable...

  • Development of Authentic Engineering Curriculum through Collaborative Development: Research on Development and Adoption

    Creator:
    Cross, Matthew J.
    Abstract:
    Background: Studies indicate that problems utilized in traditional undergraduate engineering education do not adequately prepare students for the workforce. Calls to implement authentic, ill-structured problems into upper level engineering experiences may address this issue but adopting authentic engineering problems without considering barriers to adoption of faculty has not been fully...

  • Alkali-silica reaction in concrete containing recycled concrete aggregates

    Creator:
    Adams, Matthew P.
    Abstract:
    Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...

  • Unmanned aircraft systems for bridge inspection : testing and developing end-to-end operational workflow

    Creator:
    Gillins, Matthew N.
    Abstract:
    Bridge inspections are vital for monitoring the health and serviceability of transportation infrastructure throughout the world. However, inspections can be logistically-challenging, expensive, and dangerous. For example, inspections may require climbing, as well as the use of scaffolding, ladders, rescue boats, bucket trucks, and/or under-bridge inspection vehicles. Small, multirotor unmanned aircraft...
