  • Evaluation of selected marginal aggregates stabilized with cement

    Creator:
    Chang, Chen
    Abstract:
    Coastal Oregon is deficient in quality construction aggregate. There is, however, an abundance of lower quality, or marginal aggregate available for construction purposes. The purpose of this report is to develop techniques for upgrading marginal aggregates with portland cement and methods for evaluating the relative performance of these stabilized materials...

  • Pile hammer selection by driving stress analysis

    Creator:
    Barrero-Quiroga, Franklin
    Abstract:
    This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...

  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • Evaluation of the torsion test for determining the shear strength of structural lumber

    Creator:
    Heck, Leanne Renee
    Abstract:
    The torsion test was evaluated as a method for determining the shear strength of full-size structural lumber. The evaluation involved an experimental length study, an experimental depth study, and a finite element study. The length study consisted of fifty nominal 2x4 specimens, ten specimens for each length, and ten American...

  • Development of the simplified method to evaluate dynamic mechanical analysis data on asphalt-aggregate mixtures

    Creator:
    Ab-Wahab, Yunus Bin
    Abstract:
    Testing of asphalt binders and asphalt-aggregate mixtures using dynamic mechanical analysis is becoming popular with improvements in high-speed computers, precision equipment, and computer software. Researchers are trying to describe the behavior of asphalt binders and asphalt-aggregate mixtures in terms of their time- and temperature-dependent linear viscoelastic behavior. The objectives of...

  • 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...
