  • Application of geostatistics to regional evapotranspiration

    Creator:
    Amegee, Kodjo Y.
    Abstract:
    Regionalized variable analysis has been used to study a number of meteorological and hydrological variables including precipitation (Delhomme and Delfinier, 1973), streamfiow (Villeneuve et al., 1979) and hydraulics of groundwater aquifers (Gambolati and Volpi, 1979). In the research work reported in this thesis, an attempt was made to characterize the...

  • Integrating Driving Simulator Experiment Data with Multi-Agent Connected Automated Vehicle Simulation (Ma-Cavs) Platform to Quantify Improved Capacity

    Creator:
    Chand, Cadell Y.
    Abstract:
    Autonomous vehicles (AVs) at varying market penetrations will change traffic flow and highway performance. At AV market penetrations between 0% and 100%, human driven vehicles (HVs) will be interacting with AVs. However, little is known about how HVs interact with AVs. This study attempts to quantify HV headways when following...

  • Applying climate change information to hydraulic and hydrologic transportation infrastructure

    Creator:
    Al Naabi, Rawan Y.
    Abstract:
    Scour is the main cause of bridge failures in the United States. Bridge failures raise a hazard to the safety of the traveling public as well as the massive economic consequences due to the high cost of constructing a new or a replacement bridge. The Oregon Department of Transportation (ODOT)...

  • Effectiveness of curve advisory speed signs : a characterization of road operations in western Oregon

    Creator:
    Avelar Morán, Raúl Eduardo
    Abstract:
    Posting advisory speed signs at sharp horizontal curve locations is a common practice in the U.S. These signs recommend drivers safe speeds to negotiate such curves. Literature indicates that adherence to advisory speeds is, in general, poor. Moreover, limited research is available that quantifies safety implications of these signs. This...

  • Agent-based Tsunami Evacuation Model : Life Safety and Network Resilience

    Creator:
    Mostafizi, Alireza
    Abstract:
    Natural disasters could result in unnecessary loss of life and disproportionate suffering to families and communities if evacuation plans are not in place or understood by the public. In the Pacific Northwest, a magnitude 9.0 earthquake and tsunami from the Cascadia Subduction Zone (CSZ) represents one of the most pressing...

  • Soil-bridge interaction during long-duration earthquake motions

    Creator:
    Romney, Kyle T.
    Abstract:
    Earthquake engineering analyses are often performed using shallow, crustal earthquake motions (e.g., 1940 El Centro). However, large areas of the world are subject to subduction zone earthquake motions (e.g., the Pacific Northwest). A subduction zone earthquake motion is characterized by its long duration (e.g., strong shaking lasts for more than...

  • Tsunami Loading on Coastal Infrastructure

    Creator:
    Xie, Zhongliang
    Abstract:
    The safety of coastal infrastructure has been a concern after the Indian Ocean Tsunami in 2004 and the Great East Japan Tsunami in 2011. The western coast of the United States is also exposed to tsunami hazards due to the Cascadia subduction zone. Therefore, it is critical to design coastal...

  • Monotonic and Cyclic Testing of Cross-Laminated Timber Diaphragms

    Creator:
    Beairsto, Cody J.
    Abstract:
    Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete. Large, in-plane tests on cross-laminated timber...

  • Effect of subduction zone earthquakes on SDOF bridge models

    Creator:
    Long, Yicheng
    Abstract:
    Current bridge design codes do not account for the effects of duration of mega-thrust subduction zone earthquakes. Furthermore, codes and even recent performance-based design methodologies only make use of the peak response quantities (forces, displacements, and ductility demands) and do not account for the increased number of inelastic cycles that...

  • Aseismic performance of a cable-stayed structure with decentralized H[infinity] control

    Creator:
    Chńg, Guan B.
    Abstract:
    The dissertation uses state-of-the-art structural engineering theories, in parallel with the modern and still-developing control theory of electrical engineering to mitigate the vibratory responses of a double-stayed bridge subjected to strong earthquake ground motions. First, a nonlinear finite element model of the double-stayed bridge subjected to non-uniform (multi-support) earthquake excitations...
