  • Adjacent structure response sensitivity to seismic events using the direct differentiation method

    Creator:
    White, William S.
    Abstract:
    The response of adjacent structural systems to earthquake motions is investigated using the finite element framework OpenSees. Results of sensitivity analyses demonstrate that structural response quantities can increase in either or both of the adjacent structures for specific configurations. The structural models used include steel moment-resisting frames and rigid shear...

  • Elevated Temperature Effects on the Shear Performance of a Cross-Laminated Timber (CLT) Wall-to-Floor Bracket Connection

    Creator:
    Mahr, Kolton J.
    Abstract:
    Connections in mass timber structural systems dissipate energy and transfer lateral forces from mass timber elements such as shear walls and diaphragms, providing critical load paths. Cross-laminated timber (CLT) is a prominent mass timber material used to manufacture wall and floor assemblies. Fire performance research of CLT walls and floors...

  • Shear reinforcement effects of discrete columns in liquefiable soils

    Creator:
    Rayamajhi, Deepak
    Abstract:
    Discrete columns, such as stone and soil-cement columns, are often used to improve the liquefaction resistance of loose sandy ground. In particular, stone columns are considered to increase resistance potential by densification, drainage, and reinforcement mechanisms. For silty soil, the shear stress reduction resulting from the reinforcing effect of stiffer...

  • Durability and Performance of High Early Strength Concrete for Structural Bridge Deck Overlays

    Creator:
    Smith, Jeremy A.
    Abstract:
    High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...

  • Depth-dependence of surf zone eddies : a study at Duck, NC

    Creator:
    Aiken, Rebecca A.
    Abstract:
    Surf zone eddies (f < 0.01 Hz) are important in nearshore mixing, shoreline erosion, the distribution of pollutants, and ecological processes, such as offshore transport of larvae. Surf zone eddies have traditionally been treated as two-dimensional features with horizontal length scales larger than the local water depth. Studies by Lippmann...

  • Internal curing of high-performance concrete for bridge decks

    Creator:
    Deboodt, Tyler
    Abstract:
    High performance concrete (HPC) provides a long lasting, durable concrete that is typically used in bridge decks due to its low permeability, high abrasion resistance, freeze-thaw resistance and strength. However, this type of concrete is highly susceptible to the deleterious effects of both autogenous and drying shrinkage. Both types of...

  • Practical modeling for load paths in a realistic, light-frame wood house

    Creator:
    Pfretzschner, Kathryn S.
    Abstract:
    The objective of this study was to develop and validate practical modeling methods for investigating load paths and system behavior in a realistic, light-frame wood structure. The modeling methods were validated against full-scale tests on subassemblies and an L-shaped house. The model of the L-shaped house was then modified and...

  • Light-frame versus timber frame : a study in quantifying the differences

    Creator:
    Malone, Brian P.
    Abstract:
    The objective of this study was to compare light wood framing and traditional timber framing quantitatively through environmental impact assessment and load path analysis. This research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and the design of structures considered within reflect the general characteristics...

  • Extreme Wave Runup and Runup Variability on Beaches

    Creator:
    Li, Chuan
    Abstract:
    Wave runup is an important physical process that affects nearshore sediment transport, coastal erosion, and flooding. Large and unexpected runup events can also be dangerous to beach goers. Extreme runup statistics are essential parameters used in engineering design of marine structures and in coastal management. Although the study of runup...

  • Evaluation of Topography and Seismicity on Shallow Landslide Susceptibility

    Creator:
    Hess, Daniel M.
    Abstract:
    Shallow landslides are a prevalent concern in mountainous regions that can result in severe societal, economic, and environmental impacts. The challenge is further compounded as the size and location of a potential slide is often unknown. This study presents a generalized approach for the evaluation of shallow landslide susceptibility using...
