  • Carbonation of Mid-Twentieth Century Reinforced Concrete Bridges in Oregon

    Creator:
    Folkestad, Jill Louise
    Abstract:
    Carbonation of Carbon is of concern for reinforced concrete bridges. While long-term environmental deterioration of structures is unavoidable, protective design allows a structure to fulfill its service life without any significant serviceability or strength loss due to deterioration. Understanding the process of concrete carbonation and the effect it has on...

  • The impact of powered mobility use on expressive communication development of young children with disabilities

    Creator:
    Morrison, Zoe
    Abstract:
    While the use of powered mobility devices for young children with mobility challenges has taken off in recent years following evidence that the use of powered mobility at a young age augments other traditional mobility skill interventions, the research is still limited and focuses on physical impacts more. Recently, the...

  • The Location of the Neutral Axis in Wood Beams with Multiple Knots

    Creator:
    Voigt, Levi R.
    Abstract:
    In a homogenous and isotropic material, the location of the neutral axis coincides with the location of the centroid of the beam. Wood is anisotropic, meaning that it has different properties in different directions. It is also non-homogenous, meaning that the beam exhibits different properties at different locations throughout its...

  • Streambed scour and redeposition behavior in streambed simulated culverts over an annual period

    Creator:
    Stewart, Anna
    Abstract:
    The objective of this study was to provide first order observations of bed level changes occurring in streambed simulated culverts throughout an annual period. To accomplish this, 30 culvert sites were selected in Oregon and Washington, and monitored over, at least, a 2 year period. Streambed scour and redeposition data...

  • Post-Earthquake Performance Assessment of Steel Strongback Braced Frames

    Creator:
    Rhoades, Katharine
    Abstract:
    Traditional braced frames are an efficient and economic means of resisting seismic demands. However, braced frames are prone to story mechanisms, which can result in concentrations of demands and damage during seismic events. Including steel strongbacks in conjunction with traditional braced frames can mitigate story mechanisms. The SBF results in...

  • Strength and Composition of Willamette Valley Cob: An Earthen Building Material

    Creator:
    Pullen, Quinn M.
    Abstract:
    Cob is an earthen building material composed of sand, clay and straw. Though cob homes are presently being built in the Pacific Northwest, there is no applicable building code for this material. The purpose of this study is to establish estimates for the major engineering parameters, including both average values...

  • Preliminary deployment and evaluation of geophone sensors for monitoring wave activity: GeoMoteShield

    Creator:
    Lathrop, Eve
    Abstract:
    This study focuses specifically on the investigation of a new, inexpensive geophone system and its application to monitor wave activity. Studies of seismic observations of coastal cliffs suggest that ground motions generated from local ocean waves may provide a surrogate to limited wave buoy data to quantify the wave contact...

  • Sustainability of Concrete in the Pacific Northwest

    Creator:
    Chaimov, Hilary
    Abstract:
    Reducing the CO2 emitted by the production of cement can greatly reduce the carbon emissions attributable to the built industry. By specifying concrete mixes with lower global warming potentials (GWPs), structural engineers can reduce the carbon emissions of concrete used in the built industry. This thesis uses a cradle-to-gate life...

    Abstract:
    Because of the increased need for sustainable construction in an ever urbanizing culture, new sustainable drainage systems are being developed and implemented. Bioswales are becoming an increasingly popular form of sustainable urban drainage used for parking lots and subdivisions. But little is known regarding the effectiveness of bioswales in really...
