  • Hybridized framing to modify load paths and enhance wood shearwall performance

    Creator:
    Bultena, Sarah M.
    Abstract:
    Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, and other geometries. Many heavy timber frames constructed during colonial American times are still standing, exceeding the expected...

  • Wood materials and shearwalls of older light-frame residential structures

    Creator:
    Carroll, Cameron T.
    Abstract:
    Light-frame construction practices and materials have changed greatly over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...

  • Strain distribution in OSB and GWB in wood frame shear walls

    Creator:
    Sinha, Arijit
    Abstract:
    The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objectives of the study were to: (1) evaluate qualitatively the load sharing between OSB...

  • Safety Audits: A Comparison of Traditional Safety Audits to the Interactive Highway Safety Design Model

    Creator:
    Houghton, Tegan Marie
    Abstract:
    In the United States there are currently two different options for providing safety audits to roadway projects. Traditional audits can be conducted using procedures similar to those in the United Kingdom, or those similar to Australia and New Zealand (Austroads). Another option for conducting safety audits is to use the...

  • 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...

  • Optimizing the performance of gypsum wall board in wood frame shear walls

    Creator:
    Goodall, Scott I.
    Abstract:
    The overall goal of this project was to design a wood frame shear wall that could withstand greater displacement before damage occurred to the Gypsum Wall Board (GWB). More specifically, the objectives of the study were: (1) to evaluate damage to the GWB in alternative shear wall designs at 1%,...

  • An Examination of the Neutral Axis of Wood Beams

    Creator:
    Davis, Phillip M.
    Abstract:
    For wood beams, it is often assumed that the neutral axis is located at the centroid of the beam. The neutral axis of isotropic, homogeneous materials is located at the centroid of the material, but wood is neither isotropic nor homogeneous. The varying grain patterns and knots located throughout wood...

  • 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...

  • Slotted-bolted friction damper as a seismic energy dissipator in a braced timber frame

    Creator:
    Tjahyadi, Alfred
    Abstract:
    Friction dampers have been used successfully to dissipate seismic energy in steel and concrete structures. The application is new to timber structures. The objectives of this research were to design a slotted bolted connection (SBC) and evaluate its potential as a passive energy damper in timber brace. The research was...

  • The performance of wood frame shear walls under earthquake loads

    Creator:
    White, Kevin Bradish DelGrande
    Abstract:
    The overall goal of this study is to evaluate the earthquake performance of wood frame shear walls, and more specifically: (1) to compare the performance differences of fully and partially anchored walls under monotonic, cyclic, and earthquake loads, (2) to compare wall performance under earthquake loads with that of standardized...
