  • Engineering properties of Oregon and Washington coast range soils

    Creator:
    Alto, Jalmer V.
    Abstract:
    Landslides are frequent in the steep forested regions of the Oregon and Washington coastal mountain ranges. The need for forest products has resulted in increasing logging activity in these marginally stable areas. The occurrence of landslides has increased, which in turn has focused greater interest in slope stability management. Of...

  • Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

    Creator:
    Engleson, Renee M.
    Abstract:
    Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

  • An evaluation of coastal Oregon's marginal aggregates

    Creator:
    Clemmons, Gregory H.
    Abstract:
    Coastal Oregon is deficient in quality construction aggregates. There is, however, an abundance of lower quality, or marginal, aggregate available for construction purposes. An evaluation of these marginal aggregates is the purpose of this paper. There are four classes of marginal rocks found on the Oregon Coast. Basalts, high in...

  • The Location of the Neutral Axis in Wood Beams with Multiple Knots

    Creator:
    Voigt, Levi R.
    Abstract:
    In a homogenous and isotropic material, the location of the neutral axis coincides with the location of the centroid of the beam. Wood is anisotropic, meaning that it has different properties in different directions. It is also non-homogenous, meaning that the beam exhibits different properties at different locations throughout its...

  • Tsunami Simulation Using OpenSees : Validation of Bridge Response and Exploration of Shallow Water Flow

    Creator:
    Cressman, Luke R.
    Abstract:
    The finite element software framework, OpenSees, has been used by researchers to simulate the response of structural and geotechnical systems to earthquake loading. Implementation of the Particle Finite Element Method (PFEM) has made it possible to simulate hydrodynamic forces through fluid-structure interaction (FSI) in OpenSees. To validate the FSI implementation...

  • Development of a seismic rehabilitation master plan for the Oregon State University campus

    Creator:
    Trautwein, Steven R.
    Abstract:
    The recent increase in awareness of the seismic hazards in Oregon has led to a concern regarding the safety of Oregon State University buildings. While the decision has been made to initiate the seismic rehabilitation of campus facilities, the question of which buildings pose the greatest hazards, and are therefore...

  • Evaluation of fabric reinforcement of the roadway structure

    Creator:
    Lavansiri, Direk
    Abstract:
    An evaluation of fabric reinforcement of the roadway structure is made. The study includes a parametric analy sis using layered elastic theory and a series of large scale model tests. The parametric. study analyzes the stresses and strains of roadway structures with a fabric layer between tna surface layer and...

  • Monotonic and Cyclic Testing of Cross-Laminated Timber Diaphragms

    Creator:
    Beairsto, Cody J.
    Abstract:
    Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete. Large, in-plane tests on cross-laminated timber...

  • Reassessment of Grading Criteria with Respect to the Flexural Properties of Douglas-fir Crossarms

    Creator:
    Anderson, Christopher H.
    Abstract:
    Wood plays a key role in modern electrical infrastructure; crossarms and power poles utilize the high strength to weight ratio, availability and low cost of wood to facilitate the access of power to millions of Americans. However, wood presents a variety of challenges as a material. In structural applications, one...

  • Elevated Temperature Effects on the Shear Performance of a Cross-Laminated Timber (CLT) Wall-to-Floor Bracket Connection

    Creator:
    Mahr, Kolton J.
    Abstract:
    Connections in mass timber structural systems dissipate energy and transfer lateral forces from mass timber elements such as shear walls and diaphragms, providing critical load paths. Cross-laminated timber (CLT) is a prominent mass timber material used to manufacture wall and floor assemblies. Fire performance research of CLT walls and floors...
