  • 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...

  • Influence of diagonal cracks on negative moment flexural anchorage performance in reinforced concrete bridge girders

    Creator:
    Goodall, Joshua K.
    Abstract:
    Large numbers of vintage reinforced concrete deck-girder bridges remain in the national bridge inventory. Many of these exhibit diagonal cracking and other distress. Due to the design practices of the time, it is common to observe cracks at locations where flexural reinforcing steel is terminated along the span. The presence...

  • Application of Titanium Alloy Bars for Strengthening Reinforced Concrete Bridge Girders in Flexure

    Creator:
    Vavra, Eric
    Abstract:
    Structurally efficient and cost-effective solutions are needed to extend the service-life of deficient and aging highway infrastructure around the world. One critical need is to increase the flexural strength of older reinforced concrete (RC) structures to carry heavier and more frequent loads. Titanium alloy bars (TiAB) offer a new opportunity...
