  • Direction, method, and model for implementing design for construction worker safety in the US

    Creator:
    Tymvios, Nicholas
    Abstract:
    The construction industry employs about 7% of the total US workforce, and yet it accounts for 15.7% of all occupational fatalities. Specifically in 2011, there were 721 deaths in construction, second only to transportation with 733. The cause of a large number of these construction deaths can be attributed to...

  • Reducing sediment production from forest roads during wet-weather use

    Creator:
    Toman, Elizabeth Myers
    Abstract:
    Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...

  • 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...

  • Storm runoff response from roadbuilding and logging on small watersheds in the Oregon Coast Range

    Creator:
    Hsieh, Frederic Shu-kong
    Abstract:
    The effects of roadbuilding, logging and burning upon stream runoff responses to individual storms are evaluated for the Alsea experimental watersheds, located in the Oregon Coast Range, The parameters analyzed are peak discharge, induced peak discharge, time-to-peak, and storm-runoff volume. The volume parameter is further sub-divided into total, quick, delayed,...

  • Numerical Modeling of Mass Timber Connections

    Creator:
    Hollenbeck, Sean R.
    Abstract:
    Cross-Laminated Timber (CLT) is a prefabricated building material that is relatively new to the United States and North America. It consists of no less than three layers of graded, dimensional lumber glued in alternating longitudinal and transverse layers to create a panel that can be used for various building applications...

  • A method for programming maintenance on paved forest roads

    Creator:
    Chastain, Edward Oran
    Abstract:
    The development of a pavement management system for low-volume roads is a difficult task. There are many interrelated activities that must be considered, such as planning, design, construction, maintenance, and pavement evaluation. This paper addresses the evaluation and maintenance components of a pavement management system for low-volume roadways and provides...

  • Opportunities and challenges for decision support systems in log truck scheduling and dispatching

    Creator:
    Kokenge, Kyler S.
    Abstract:
    The transportation of logs from the forest to the mill accounts for 25-50% of the delivered cost of wood, depending mostly on haul distance. Decision support systems (DSS) for log truck scheduling and dispatching have the potential to reduce transportation costs by optimally constructing routes, also known as schedules for...

  • Engineering Services of Submerged Aquatic Vegetation (SAV): Investigation of the Land-Building and Energy-Attenuating Properties of SAV Habitats Across Spatial Scales

    Creator:
    Holzenthal, Elizabeth R.
    Abstract:
    Submerged aquatic vegetation (SAV) species, such as seagrasses, are highly valued in estuaries because of the many economic, ecological, and cultural services that they provide, including shelter for fisheries, minimizing water turbidity, and improving am-bient water quality. SAV can also alter its physical environment by attenuating wave and current velocities,...

  • Reliability-based Serviceability Limit State Design Procedures for Shallow Foundations

    Creator:
    Huffman, Jonathan C.
    Abstract:
    Reliability-based geotechnical foundation design focusses on soil and structure analysis that meets necessary safety, performance and/or serviceability criteria, calibrated based on probabilistic analyses and an accepted level of risk. As the civil engineering community seeks to better harmonize geotechnical and structural design methodologies, reliability-based design is being incorporated more into...
