  • The role of alumina in the mitigation of alkali-silica reaction

    Creator:
    Warner, Skyler J.
    Abstract:
    The use of fly ash as a supplementary cementitious material (SCM) has increased in the last century due to its various environmental benefits as a recycled product. Within the last 60 years, it has been found that it can be used to effectively control damage induced by Alkali-Silica Reaction. However,...

  • An Investigation of Student Cognitive Engagement in the STEM Classroom—A Compilation of Faculty and Student Perspectives

    Creator:
    Barlow, Allyson J.
    Abstract:
    Student engagement has been the focus of much engineering education research, in large part due to its ties to student learning. Widely considered to be a meta-construct, student engagement is often broken down into behavioral, emotional, and cognitive components. Reasons for ongoing research on student cognitive engagement are twofold: educators...

  • 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...

  • 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...

  • Risk and reliability associated with use and reuse of vertical formwork

    Creator:
    Das, Amrutha
    Abstract:
    Concrete formwork is a common type of temporary structure used on construction projects. Due to difficulties in considering actual construction site implications during formwork design, assessments of formwork integrity are often made in the field by site personnel based on subjective visual inspection. The use and re-use of concrete formwork...

  • Investigation of x-ray computed tomography for Portland cement phase quantification

    Creator:
    Deboodt, Tyler J.
    Abstract:
    Cementitious materials are often characterized through the use of advanced analytical techniques to understand the macro-, micro-, and nano-scale properties, including phase formation during hydration, and subsequent potential deterioration mechanisms which can affect service life. A major limitation with using such analytical techniques to quantify solid phases in cementitious systems...

  • Performance Based Tests on Cross Laminated Timber - Concrete Composite Floor Panels

    Creator:
    Blank, Curtis
    Abstract:
    This project determines the short term and long term effective stiffness values for Cross Laminated Timber (CLT) with a reinforced concrete topping. The reinforced concrete was attached to the CLT panels with interface connections, and different types of interface connections were tested. Throughout this project, there are 31 tests with...

  • Unmanned aircraft systems for bridge inspection : testing and developing end-to-end operational workflow

    Creator:
    Gillins, Matthew N.
    Abstract:
    Bridge inspections are vital for monitoring the health and serviceability of transportation infrastructure throughout the world. However, inspections can be logistically-challenging, expensive, and dangerous. For example, inspections may require climbing, as well as the use of scaffolding, ladders, rescue boats, bucket trucks, and/or under-bridge inspection vehicles. Small, multirotor unmanned aircraft...

  • Examination of lateral stiffness and strength of pitched residential roof diaphragms with implications for seismic design.

    Creator:
    Kirkham, William J.
    Abstract:
    There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...

  • Behavior of open grid steel bridge decks under service and fatigue loads

    Creator:
    Fetzer, Peter C.
    Abstract:
    Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure continues to deteriorate, open grid decks can be used as a cost effective way to rehabilitate structurally deficient...
