  • GOSEP: Georeferenced Oregon Soil Engineering Properties

    Creator:
    Dutille, Victoria L.
    Abstract:
    Geotechnical engineers design and analyze the interface between the natural and built environments, often based on uncertain and inherently variable data due to the nature of the building material, soil. Engineers must estimate the subsurface conditions at a site using historical, in-situ, and laboratory testing data. However, only discrete representative...

  • 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...

  • An investigation of Oregon weight-in-motion data for bridge rating implementation and evaluation

    Creator:
    Pelphrey, Jordan Michael
    Abstract:
    The LRFR Manual, within commentary Article C6.4.4.2.3, contains provisions for development of site-specific live load factors. In Oregon, truck Weigh-in-Motion (WIM) data were used to develop live load factors for use on state-owned bridges. The factors were calibrated using the same statistical methods that were used in the original development...

  • Large scale model testing of the FMC submerged wave attenuation device

    Creator:
    Huber, David S.
    Abstract:
    This report describes the hydrodynamic testing and evaluation of a one-tenth scale model of the FMC Wave Attenuation Device. The purpose of the test was to quantify the wave attenuation characteristics and structural loading induced by a test program of monochromatic incident waves on the submerged structure. The device was...

  • Flexible membrane wave barrier

    Creator:
    Thompson, Gary O.
    Abstract:
    This report details the derivation of an analytical model for a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column by a moored cylindrical buoy on the free surface and fixed to a hinge at the seafloor. The analytical model combines...

  • Cyclic triaxial testing of low- to moderate-plasticity silts

    Creator:
    Butler-Brown, Jason J.
    Abstract:
    This project report presents a laboratory investigation of the dynamic behavior of saturated alluvial silty soils from sites in Oregon and Washington. The focus of the study was to document the liquefaction susceptibility, post cyclic strength, and volumetric strain behavior of the silt soils based on cyclic, undrained triaxial compression...

  • Requirements for successful irrigation systems in the Senegal River Basin (Mauritania)

    Creator:
    Abba, Fatima Zahra
    Abstract:
    Implementation of a small-scale irrigation project in southern Mauritania is analyzed in this report. The main objective is to demonstrate that small-scale irrigation farming is the best suited solution for Mauritania's agriculture. To reach this objective different steps are taken in this study. The first step highlights the different aspects...

  • The effect of boundary geometry on internal density currents in a density stratified reservoir

    Creator:
    Spurkland, Torbjorn
    Abstract:
    The effects of boundary geometry on internal density currents in a density stratified reservoir were investigated in a laboratory model. When water was simultaneously withdrawn and admitted to the reservoir, a complex current regime was established. The general flow pattern is described, and the influence of physical variables on the...

  • 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...

  • Consistency and effectiveness of advisory speeds: an evaluation of current posting techniques

    Creator:
    Rohani, Joshan W.
    Abstract:
    Crash rates are said to be nearly three times higher on curved sections than those on straight sections of rural roadways. As a result, advisory curve/speed signs are standard practice to mitigate these risks on sharp horizontal curves. The industry standard for determining appropriate and uniform speeds for such signs...
