  • Experimental and Analytical Studies of Large-Scale Pile Caps

    Creator:
    Al-Sakin, Yasmeen
    Abstract:
    Pile caps are structural elements used to transfer loads from columns to a group of piles, which transfer them to stronger soil layers. Pile cap with horizontal distance between the column and piles less than twice its effective depth is categorized as "deep," where significant nonlinear strain distribution occurs through...

  • Observations and Modeling of Shear Reduction and Sediment Flux within Vegetated Canopies on Managed Coastal Dunes

    Creator:
    Dickey, John
    Abstract:
    Wind flow on vegetated coastal foredunes adapts to the local canopy drag, resulting in spatial gradients in bed shear stresses which contribute to the formation of localized bedforms (e.g., nebkha, shadow dunes). Numerous morphological properties of the plants, including canopy height and density, affect the wind flow dynamics and therefore...

  • Effects of soil slope on lateral capacity of piles in cohesive soils

    Creator:
    Nimityongskul, Nontapat
    Abstract:
    Pile supported bridges are typically constructed near or in a natural or man-made slope and are subjected to lateral loading. The current design method for laterally loaded piles involves the use of Winkler's spring concept with the standard nonlinear p-y curves. The available p-y curves were developed based on results...

  • Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

    Creator:
    Mustafa, Nizar Ahmad
    Abstract:
    Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...

  • Advancements Toward the Simulation of Steel Structures in Fire Using OpenSees

    Creator:
    Gordon, James A.
    Abstract:
    Since the collapse of World Trade Center building number seven (WTC7), significant research has been done to understand the behavior of steel structures in fire and enable engineers to account for the behavior of steel framing systems exposed to fire during design. Despite these efforts, there are still significant barriers...

  • Bottleneck detection in modular construction factories using computer vision

    Creator:
    Panahi, Roshan, Louis, Joseph, Podder, Ankur, Swanson, Colby, and Pless, Shanti
    Abstract:
    The construction industry is increasingly adopting off-site and modular construction methods due to the advantages offered in terms of safety, quality, and productivity for construction projects. Despite the advantages promised by this method of construction, modular construction factories still rely on manually-intensive work, which can lead to highly variable cycle...

  • 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...

  • Networked Multi-agent Modeling of Connected Vehicles in Mixed Traffic Environment: A Decentralized Consensus Approach

    Creator:
    Wahid, Merih
    Abstract:
    Transportation systems are facing safety and operational challenges with a cost of billions of dollars annually in lost production time and wasted fuel. Infrastructure expansion, previously held as a panacea to most transportation challenges has lost its appeal due to financial, land-use and environmental constraints. Interest is surging in intelligent...

    Creator:
    Liu, Lu
    Abstract:
    Short-term freeway traffic speed prediction is essential to improving mobility and safety. It has been a challenging, yet unresolved issue. Traffic speed prediction can be applied to enhance the intelligent freeway traffic management and control for applications as operational and regulation planning. For example, with more reliable traffic speed prediction,...

  • Stochastic Characterization of Highway Capacity and Its Applications

    Creator:
    Dong, Shangjia
    Abstract:
    Highway capacity has traditionally been treated as deterministic. In reality, however, capacity can vary from time to time and location to location due to inclement weather, various driving behavior, traffic incident, bottleneck and workzone. This thesis aims to characterize the stochastic variations of highway capacity, and explore its applications. The...
