  • 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...

  • Proof of Concept for a Three-Dimensional Molded Core Wood-Strand Sandwich Panel

    Creator:
    Way, Daniel
    Abstract:
    Sandwich composites are typically produced from two high strength facings bonded to a lower strength, lightweight core. Sandwich design has proven to be efficient for applications demanding high strength and low weight. Wood-based sandwich composites have been largely limited to non-structural applications with the exception of structural insulated panels and...

  • The effect of biological deterioration on the performance of nailed oriented strand board sheathing to Douglas-fir framing member connections

    Creator:
    Kent, Scott M.
    Abstract:
    Service life prediction models for light-framed wood structures require an extensive quantity of empirical data on deterioration pathologies for the numerous structural components, as well as mechanistic approaches to determine their capacity at various levels of deterioration. The data and models presented in this study satisfy a portion of the...

  • Evaluation of the torsion test as a method to determine the shear strength of structural composite lumber

    Creator:
    Siller, Tobias Stefan
    Abstract:
    Torsion test was evaluated as a method to determine the shear strength parallel to grain of full-size structural composite lumber (SCL). Experimental results of eighty-five rectangular (44 x 140 mm²) specimens were verified by finite element analysis. Laminated strand lumber (LSL), laminated veneer lumber (LVL) and parallel strand lumber (PSL)...

  • Use of Virtual Visual Sensors in the Determination of Natural Frequencies of Timber Structures for Structural Health Monitoring

    Creator:
    Walker, Kristopher
    Abstract:
    Many nondestructive techniques for structural health monitoring are subjective and based on visual observations of degradation. In addition, dynamic properties of structures are already used to obtain quantitative structural health data. However, most current data collection is limited to localized damage on the structure, rather than global response. Recent research...

  • An examination of strategic challenges and opportunities in the wood-based building product industry

    Creator:
    Tokarczyk, John A.
    Abstract:
    The wood-based building products industry has experienced significant turbulence over the past several decades as a function of multiple forces including among others globalization, product and process innovation, and shifting customer and consumer interest and demands. Collectively, these changes have challenged the historical tenets which have defined industry strategy and...

  • Tsunami loading on light-frame wood structures

    Creator:
    Linton, David B.
    Abstract:
    Since 2004 there have been multiple devastating tsunamis around the globe triggered by large magnitude earthquakes; with the most recent being the Tohoku, Japan tsunami in March 2011. These tsunamis have caused significant loss of life and damage to the coastal communities impacted by these powerful waves. The resulting devastation...

  • Copper compounds for durable composites : effects on material properties

    Creator:
    Vidrine, Cheney L.
    Abstract:
    The effects of incorporation of selected biocides on physical and mechanical properties of aspen strandboard were assessed using five copper-based preservatives or zinc borate at three retention levels. Tebuconazole or 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one (DCOI) were added as co-biocides to selective copper-based treatments. Mold box tests showed that only panels treated with DCOI...

  • The effects of nail bending-yield stress and biological deterioration on the cyclic performance of shearwalls

    Creator:
    Anderson, Erin N.
    Abstract:
    Key parts of the lateral force resisting system in wood-frame buildings are the shearwafls and the connections. The connections in wooden buildings are the primary source of ductility and energy dissipation; these are essential properties when buildings are exposed to lateral forces, such as wind and earthquakes. Shearwall design is...

  • 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...
