  • Post-wildfire Investigation of Civil Infrastructure Following the 2018 Camp Fire

    Creator:
    Schulze, Stefanie S.
    Abstract:
    Wildland-urban interface (WUI) communities, where forested land boundaries or intermixes with infrastructure, are quickly growing in the US. WUI communities have grown substantially from 1990 to 2010, with an increase of 12.7 million houses and 25 million people. Wildfires encroaching on WUI communities can cause damage to both above ground...

  • On the Imaging of Rip Currents in X-band Radar

    Creator:
    Kloster, Rebecca
    Abstract:
    Rip currents pose a serious danger to visitors of bathing beaches; they are also an important process in surf zone circulation. Haller et al. [2014] demonstrated that shore-based X-band radar can be used to compliment in situ measurements of rip currents. However, little is known of the underlying radar imaging...

  • Depth estimation and frontal imaging via X-band marine radar

    Creator:
    Honegger, David Andrew
    Abstract:
    This dissertation focuses on two core aspects of remote sensing: (a) interpretation of the remotely sensed data to identify and characterize sea surface features of interest, and (b) the quantitative analysis of previously characterized features to produce robust estimates of geophysical variables. Specifically, these aspects are addressed in the context...

  • Investigation of x-ray computed tomography for Portland cement phase quantification

    Creator:
    Deboodt, Tyler J.
    Abstract:
    Cementitious materials are often characterized through the use of advanced analytical techniques to understand the macro-, micro-, and nano-scale properties, including phase formation during hydration, and subsequent potential deterioration mechanisms which can affect service life. A major limitation with using such analytical techniques to quantify solid phases in cementitious systems...

  • The Evaluation of Cementitious Pore Solution Composition and Electrical Resistivity Using X-ray Fluorescence (XRF)

    Creator:
    Tsui Chang, Marisol
    Abstract:
    Interest in performance specifications has been growing in the civil and construction industry in the past decade. One major focus area has been on understanding how to prolong the service life of concrete structures, since repair and rehabilitation of existing infrastructure have cost many trillions of dollars. Deterioration mechanisms such...

  • The effect of hold-down misplacement on the strength and stiffness of wood shear walls

    Creator:
    Lebeda, Dana J.
    Abstract:
    The objective of this study was to determine the effect of misplaced hold-downs on the static and cyclic behavior of wood shear walls. Three shear wall configurations were considered in this study. The first configuration (control) had hold-downs at the ends of the wall (wall type 1), the second configuration...

  • Hydrodynamic loads on fiber-optic micro cables

    Creator:
    Evans, Matthew R.
    Abstract:
    A Finite Element Model of a deployed Fiber-Optic Micro Cable (FOMC) was performed using the marine cable modeling software, OrcaFlex. The focus of this study was a parametric analysis of a two-part, towed cable array with the FOMC dragged behind a depressor and connected to a drogue chute. Length-to-diameter ratios...

  • From Perception to Planning : Adaptation in Flood-risk Communities

    Creator:
    Gomez, Luis A.
    Abstract:
    This research asserts that flood risk perception of individuals living in floodplains influences their preparedness for taking actions to protect themselves from flood hazards. The results of this research are backed up by quantitative analysis of survey responses of individuals living in floodplains of Corvallis, OR in the USA. The...

  • Demonstration of a permeable barrier technology for the in-situ bioremediation of pentachlorophenol contaminated groundwater

    Creator:
    Cole, Jason David
    Abstract:
    A pilot scale demonstration of a biological permeable barrier was conducted in a pentachlorophenol-contaminated aquifer at a wood preserving facility. A permeable reactor was constructed to fit within a large diameter well. Arranged in series, a cylindrical reactor 24" x 36" (0.61 x 0.91m) (diameter x height) was partitioned to...

  • Performance of partially and fully anchored wood frame shear walls under monotonic, cyclic and earthquake loads

    Creator:
    Seaders, Peter
    Abstract:
    The objectives of this study were to evaluate the performance of wood frame shear walls under monotonic, cyclic and earthquake loads by: (1) estimating the variability of shear wall performance, (2) comparing the performance of walls under each loading protocol, (3) evaluating the effects of anchorage on wall performance, and...
