  • Height Modernization from Static GPS Networks in Oregon: Evaluating NGS Guidelines and OPUS-Projects

    Creator:
    Kerr, Darren J.
    Abstract:
    Determining accurate elevations is important for many engineering and scientific applications, and finding these heights via GNSS increases efficiency and significantly reduces the costs as compared to precise geodetic leveling. The National Geodetic Survey (NGS) has published guidelines for determining both ellipsoidal and orthometric heights with GPS to within 2...

  • Numerical assessment of steel plate shear wall with coupling (SPSW-WC) system design procedure

    Creator:
    Li, Wennan
    Abstract:
    The Steel Plate Shear Wall (SPSW) system, is an innovative seismic lateral force resistant system, which has experienced increased use over the last three decades. The SPSW system is composed of boundary elements which anchor web plates that develop diagonal tension fields. A number of SPSW buildings have been built...

  • Bridge Damage State Detection Based on Strain-Based Wireless Structural Health Monitoring

    Creator:
    Slaven, Kelli R.
    Abstract:
    The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges...

  • Hybrid Survey Networks : Combining Real-time and Static GNSS Observations for Optimizing Height Modernization

    Creator:
    Weaver, Brian Jerald
    Abstract:
    To derive ellipsoid heights on passive marks with cm-level accuracy, many current specifications require the collection and adjustment of long-duration, static Global Navigation Satellite System (GNSS) sessions. To increase efficiency, a survey procedure that includes real-time kinematic vectors from a real-time GNSS network (RTN) was evaluated. Thirty different “hybrid” networks...

  • Evaluation of the Performance of Lateral Spread Displacement Empirical Models for Subduction Zone Earthquake Case Histories

    Creator:
    Bunn, Michael
    Abstract:
    Lateral spread is a pervasive type of liquefaction-induced ground failure that occurs on gentle slopes or near free-faces, such as river channels. Resulting horizontal displacements can reach up to several meters, and can be considerably damaging to foundations, bridges, roadways, pipelines, etc. In the 1990s, Bartlett and Youd (1992a, 1995)...

  • Small Unmanned Aircraft Systems (UAS) for Engineering Inspections and Geospatial Mapping

    Creator:
    Javadnejad, Farid
    Abstract:
    Small unmanned aircraft systems (UAS) carrying consumer-grade nonmetric cameras are increasingly utilized to generate high-resolution 3D geospatial data. Low cost, ease of operation, widespread availability and low altitude maneuvering capabilities of UAS, as well as the rapid development of technology and methods, make UAS-based photogrammetry applicable to many civil engineering...

  • Observations and prediction of intermittent sediment suspension in the surf zone

    Creator:
    Yoon, Hyun Doug
    Abstract:
    In this dissertation the interactions between hydrodynamics, sediment suspension and transport, and morphological evolution in the surf zone was investigated with a large-scale laboratory experiment data, CROss-Shore Sediment Transport Experiment (CROSSTEX). The data set included comprehensive measurements of water surface elevation, fluid velocity, sediment concentration, and morphology for irregular waves...

  • Physical Modeling of Progressive Damage and Failure of Wood-Frame Coastal Residential Structures Due to Waves and Surge Forces

    Creator:
    Duncan, Sean M.
    Abstract:
    A physical model study was performed to examine the forces and response of 1:6 scale wood-frame coastal residential structures subjected to storm surge and waves. An on-grade and an elevated specimen were tested and exposed to regular waves with varying water depths and wave heights to simulate Hurricane Sandy’s conditions....

  • Effects of Wave Nonlinearity and Vertical Variation of Vegetation Density on Wave Attenuation

    Creator:
    Wu, Wei-Cheng
    Abstract:
    The understanding and prediction how coastal wetland vegetation attenuates wave action has received renewed attention with global climate change impacts and increasing populations on coastlines. Conventional attenuation models utilize empirical drag coefficients, but these coefficients exhibit a wide range of values, and there is some uncertainty in the relative importance...

  • Performance-Based Design Methodology for Using Emergent Vegetation to Mitigate Wave Overtopping

    Creator:
    Ostrow, Kayla
    Abstract:
    To facilitate the design of Natural and Nature-Based Features (NNBF) for flood protection, this thesis expands an existing engineering design methodology to NNBF systems. The existing approach is a Level III reliability method for the performance-based design of traditional coastal engineering systems. The expanded methodology incorporates uncertainties inherent to both...
