  • Enhancing Design of Geosynthetic-Reinforced Soil Supporting Spread Footings

    Creator:
    Xie, Yonggui
    Abstract:
    Internal stability of Geosynthetic-Reinforced Soil (GRS) walls are conventionally assessed using lateral earth pressure methods. Determination of these pressures is a key component of limit state design as it enables determination of mobilized resisting forces in reinforcements needed to ensure stability and function of the GRS structure. However, conventional methods...

  • 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...

  • Seismic Performance of Retrofitted Reinforced Concrete Columns Including Soil Structure Interaction

    Creator:
    Parson, Lance
    Abstract:
    There are many existing bridges around the world that were designed without consideration for seismic effects. Many of these bridges were designed before modern earthquake engineering design standards and practices existed and thus are expected to perform poorly during strong ground shaking. Common structural deficiencies are found in their reinforced...

  • Improving Region-Scale Landslide Inventory and Susceptibility Mapping

    Creator:
    Bunn, Michael D.
    Abstract:
    Landslides are a natural hazard that have major societal, economic, and environmental impacts. The understanding of landslides begins with the observation that they are a spatial problem. Spatial relationships have historically been explored with maps, and landslides are no different. Such maps range in focus from inventory maps, which identify...

  • 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...

  • 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...

  • 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...

  • The role of alumina in the mitigation of alkali-silica reaction

    Creator:
    Warner, Skyler J.
    Abstract:
    The use of fly ash as a supplementary cementitious material (SCM) has increased in the last century due to its various environmental benefits as a recycled product. Within the last 60 years, it has been found that it can be used to effectively control damage induced by Alkali-Silica Reaction. However,...

  • Effects of soil slope on the lateral capacity of piles in cohesionless soils

    Creator:
    Barker, Paul D.
    Abstract:
    Deep foundations, including driven piles, are used to support vertical loads of structures and applied lateral forces. Many pile supported structures, including bridges, are subjected to large lateral loads in the form of wind, wave, seismic, and traffic impact loads. In many practical situations, structures subjected to lateral loading are...

  • Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

    Creator:
    Johnson, Brandon Ang
    Abstract:
    Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...
