  • Moisture effects on properties of wood-composite assemblies

    Creator:
    King, David
    Abstract:
    Engineered wood composites are used in many structural applications and are intended for dry use. However, these materials may encounter significant amounts of wetting while in service, which can lead to structural failures. This study combined aspects of wood science, mechanics, structural engineering, and mycology to assess changes in material...

  • Effect of Hole Edge Distance on Strength of Through-Bored Utility Poles

    Creator:
    Romanaggi, Bennett T.
    Abstract:
    There are over 130 million wood poles supporting electrical transmission and distribution lines in the U.S. The vast majority of these poles are preservative treated to prolong their useful life. In some cases, however, the depth of treatment is relatively shallow, leaving a deep zone of moderately durable, untreated heartwood....

  • 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...
