  • Wave runup : Physics, variability, and societal impacts

    Creator:
    García Medina, Gabriel
    Abstract:
    The U.S. Pacific Northwest is home to one of the most extreme wave climates in the world with waves of 10 m in height arriving to the coast approximately each year. With an average water temperature of 12℃, the beaches in the region are too cold to go on a...

  • Structural Response of High-Performance Fiber-Reinforced Cementitious Composites: Evaluation, Simulation, and Sensitivity Analysis

    Creator:
    Khlef, Feras L.
    Abstract:
    The constitutive behavior of high-performance fiber-reinforced cementitious composites (HPFRCCs) under mechanical loading is characterized by significant tensile properties that play an essential role in the structural response of several applications in structural engineering. The significance of tensile properties of HPFRCCs in structural engineering is the focus of three manuscripts presented...

  • 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...

  • 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...

  • A stochastic precipitation event model for use in erosion simulations

    Creator:
    Istok, J. D.
    Abstract:
    Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...

  • Experimental and analytical evaluation of conventionally reinforced deck-girder bridge bent caps with vintage details

    Creator:
    Senturk, Ahmet Ekin
    Abstract:
    Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...

  • Coastal Soil and Structure Behavior during Earthquake-Tsunami Multi-Hazards

    Creator:
    Qiu, Yingqing
    Abstract:
    Coastal multi-hazards, i.e., earthquakes followed by tsunamis, induce severe damage to coastal infrastructure. The multi-hazards can cause soil liquefaction, which is one of the major concerns for evaluating sediments transport potential and structure failure mechanisms. The objectives for this work is threefold. First, to build and validate a soil numerical...

  • An Integrated Conceptual Framework for Sustainable Public Housing

    Creator:
    Sharafeddin, Asma
    Abstract:
    Public housing (PH) provides a substantial portion of the housing in both developed and less developed countries, and the demand for it is increasing. The PH projects, however, are facing many challenges that are affecting their performance and cause their failures. The United States has demolished large portions of their...

  • Centrifuge Modeling of Soil Response to Tsunami-like Rapid Flooding and the Subsequent Drawdown

    Creator:
    Exton, Margaret C.
    Abstract:
    Soil instability from tsunami hazards causes substantial damage to coastal infrastructure (e.g., the damage caused by the 2011 Great East Japan Tsunami, or the Heisei Tsunami). Tsunamis are unpredictable, so it is difficult to obtain field-scale measurements. Simulating tsunamis in a laboratory setting is therefore important to further understanding of...

  • Climate Change Impacts to Estuarine Hydrodynamics: Tools, Methodologies, and Predictions

    Creator:
    Parker, Kai A.
    Abstract:
    Coastal communities in the U.S. Pacific Northwest (PNW) are rapidly engaging with the idea that hazards and environmental pressures are changing and may be characteristically different in the near future. This has led to a need for scientific knowledge and tools that can help coastal communities prepare and build resilience...
