  • Practical modeling for load paths in a realistic, light-frame wood house

    Creator:
    Pfretzschner, Kathryn S.
    Abstract:
    The objective of this study was to develop and validate practical modeling methods for investigating load paths and system behavior in a realistic, light-frame wood structure. The modeling methods were validated against full-scale tests on subassemblies and an L-shaped house. The model of the L-shaped house was then modified and...

  • Evaluation of system effects and structural load paths in a wood-framed structure

    Creator:
    Martin, Kenneth G.
    Abstract:
    The objective of this project was to develop an analytical model of a light-framed wood structure using a prevalent structural analysis computer program in order to evaluate system effects and define load paths within the structure, especially under extreme wind events. Simplified modeling techniques and material definitions were developed and...

  • Load Path Investigation in a Light-Frame Wood House with Complex Geometry

    Creator:
    Holman, Justin D.
    Abstract:
    The objective of this study was to investigate load paths in an existing light-frame wood structure with complex geometry, using previously established computer modeling methods. The structural model is derived from an existing, multi-level residence located in Corvallis, Oregon. For the purpose of this study, the existing structure was simplified...

  • 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...

  • 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...

  • 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...

  • Evaluation of remediation techniques for circular holes in the webs of wood I-joists

    Creator:
    Polocoser, Tiberiu
    Abstract:
    The objective of this project was to evaluate methods to remediate a wood I-joist with a single, circular hole in the web while leaving utilities in place. The methods were experimentally evaluated with a full-scale bending test using four equally spaced point loads. There were three depths of joists with...

  • The effect of elevated temperature on mechanical behavior of structural wood and wood-based composites

    Creator:
    Sinha, Arijit
    Abstract:
    Engineers, in practice, are often faced with the challenge of evaluating a fire-damaged structure and developing a rehabilitation and retrofit plan. In order to decide on a rehabilitation and retrofit plan, information on thermal degradation of building materials and connections are vital. A critical knowledge gap exists in terms of...

  • Light-frame versus timber frame : a study in quantifying the differences

    Creator:
    Malone, Brian P.
    Abstract:
    The objective of this study was to compare light wood framing and traditional timber framing quantitatively through environmental impact assessment and load path analysis. This research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and the design of structures considered within reflect the general characteristics...

  • Development of rapid visual screening tool for seismic evaluation of wood-frame dwellings

    Creator:
    Lucksiri, Kraisorn
    Abstract:
    During the past several decades, earthquakes have caused extensive damage to buildings, including wood-frame, single-family dwellings, in the United States. In order to mitigate future losses, existing buildings in earthquake prone areas should be evaluated for their seismic safety. This is also an important issue for buildings in Oregon due...
