  • Analysis of waves in the near-field of wave energy converter arrays through image processing

    Creator:
    Black, Colleen
    Abstract:
    Oregon State University conducted a series of laboratory experiments to measure and quantify the near-field wave effects caused within arrays of Wave Energy Converters (WEC). As the waves and WECs interact, the WECs generate radiated waves; these effects vary with the location within the array. Analyzing the near-field waves will...

  • 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...

  • Behavior of Steel Structures in Fire Following Earthquakes

    Creator:
    Maddalozzo, Walker A.
    Abstract:
    Fire following earthquake (FFE) events are cascading hazards that have caused great damage in the past and pose a continued threat to our communities. The increased risk for fire after a seismic event stems from potential damage to utilities such as gas or fuel pipelines, which can lead to ignition....

  • Experimental Testing of Glue-Laminated Beam-to-Column Connections

    Creator:
    Madland, Haley
    Abstract:
    The behavior of mass timber beam-to-column connections under seismic loading is not yet well understood. Mass timber beam-to-column connections must have the ability to maintain load-carrying capacity despite the deformations that will be imposed on all components of the building during seismic events. This behavior is called deformation compatibility. The...

  • Shear capacity assessment of corrosion-damaged reinforced concrete beams

    Creator:
    Farrow, William C.
    Abstract:
    The research presented here is a study to determine the effect of shear reinforcement corrosion on the shear capacity in conventionally reinforced concrete (CRC) bridge elements. A total of 14 CRC beams were tested using three stirrup spacings (8, 10, and 12-inch). Six of the beams included the influence of...

  • Image rectification tool for evaluation of gusset plate connections in steel truss bridges

    Creator:
    Nguyen, Quang D.
    Abstract:
    A methodology was developed to permit rectification and metrification of digital images of steel truss gusset plate connections. The approach will enable rapid and accurate collection of field measurements as compared to traditional methods to enable structural evaluation of gusset plate connections. The program enables the operator to quickly create...

  • Radar and Optical Remote Sensing of Submesoscale Frontal Features

    Creator:
    Simpson, Alexandra J.
    Abstract:
    The coastal region is home to many types of surface fronts that exist on a submesoscale (1-10 $km$). While in situ observations capture point or transect observations of frontal behavior subsurface, their complex spatial patterns can be well-captured using remote sensing techniques, which provide synoptic views of the ocean surface...

  • The degradation of kraft pulping wastes in estuarine waters

    Creator:
    O'Neal, Gary Lewis, 1938-
    Abstract:
    The degradation of kraft pulping wastes in estuarine waters was measured in terms of the following parameters: five-day 20°C B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel (Mytilus edulis L.). The waste tested was the total effluent from a combined pulp and paper mill producing 430 tons of...

  • On the nearshore impact of wave energy converter arrays

    Creator:
    O'Dea, Annika Magnuson
    Abstract:
    Radiation stresses, defined as the excess flow of momentum due to the presence of waves (Longuet-Higgins, 1964), are the main drivers behind the cross-shore and longshore forcing that results in wave setup, set-down, and longshore currents (e.g. Svendsen, 2006). Longshore currents entrain and transport sediment and therefore play an important...

  • Advancements Toward the Simulation of Steel Structures in Fire Using OpenSees

    Creator:
    Gordon, James A.
    Abstract:
    Since the collapse of World Trade Center building number seven (WTC7), significant research has been done to understand the behavior of steel structures in fire and enable engineers to account for the behavior of steel framing systems exposed to fire during design. Despite these efforts, there are still significant barriers...
