  • High Strength Reinforcing Bars : Concrete Shear Friction Interface Behavior

    Creator:
    Nielson, Drew R.
    Abstract:
    Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...

  • The use of LiDAR to identify forest transportation networks

    Creator:
    Beck, Storm J. C.
    Abstract:
    The production of high value non-conventional products, such as long utility poles; or the production of low value bulky products, such as chips or grindings; provide opportunities for forest owners to increase value from their forests. The transport of these products requires the use of specialized trucks and trailers. However,...

  • 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...

  • Land surface energy balance and surface soil moisture variation in HAPEX-MOBILHY

    Creator:
    Nichols, William E.
    Abstract:
    The HAPEX-MOBILHY regional experiment provided an significant opportunity to analyze the partition of energy and distribution of water over land surfaces. The combination of remotely sensed data and ground instrument networks over the large-scale in situ experiment allowed investigation of spatial and temporal variation of such hydrologic parameters as the...

  • Data assessment in Oregon for SafetyAnalyst based on Highway Safety Manual Part B

    Creator:
    Li, Meng
    Abstract:
    The author of the Highway Safety Manual (HSM) Part B developed a predictive method for safety management. A software tool for highway safety system analysis called the SafetyAnalyst is developed basing on HSM Part B. The author describes an effort to evaluate the feasibility of SafetyAnalyst in Oregon. Seven sample...

  • Assessing the Trade-Off Between Sustainability and Resiliency of Reinforced Concrete Alternatives in Corrosive Conditions: An LCA-System Dynamics Approach

    Creator:
    Moreno Rangel, Erick D.
    Abstract:
    Concrete has been categorized as a key contributor of CO2 (carbon) emissions into the atmosphere. This is mostly associated with the production of ordinary portland cement (OPC). The concrete and cement industries are pursuing a path to reduce their carbon emissions generally in accordance with the climate change goals outlined...

  • Low volume grade crossing treatments for the Oregon high speed rail corridor

    Creator:
    Zaworski, David D.
    Abstract:
    This study defines the information gathering and communication and response needed for safety at highway-rail crossings. It examines technologies for low-cost, high-safety treatments for low volume highway crossings of higher speed (130-200 kph) rail. Crossing closure and consolidation is a necessary first step. Existing train control and crossing safety systems...

  • Groundwater flow model for the lower Malheur Basin near Ontario, Oregon

    Creator:
    Walker, David S.
    Abstract:
    The shallow, poorly-confined, sand and gravel aquifer underlying the lower Malheur River basin is contaminated by nitrate and metabolites of the herbicide dimethyl tetrachloroterephthalate (DCPA), first detected in 1983 and 1985, respectively. The aquifer supplies water for the Ontario municipal water system, domestic and industrial uses, and irrigation. In response...

  • Roughness and geometry effects of engineered log jams on 1-D flow characteristics

    Creator:
    Valverde, Rachelle S.
    Abstract:
    The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

  • Tsunami propagation in large rivers : idealized cases and the Columbia River Estuary

    Creator:
    Kalmbacher, Kirk D.
    Abstract:
    The hazards associated with tsunamis are well known and have been studied for decades. The majority of research is, however, focused on open coastlines which bear the brunt of a tsunamis force. Other regions that can be strongly impacted by a tsunami are large estuaries. Here, the tsunami encounters a...
