  • A portable geographic information system used to develop an integrated facility management support system for a military installation

    Creator:
    Kennedy, David R. (David Richard)
    Abstract:
    The combination of increased training tempo due to military base closures and the reduction in military budgets have placed a severe burden on the infrastructure at many military installations and emphasized the need for an integrated facility management support system. This research involved linking existing facility, environmental, and operational data...

  • Construction risks allocation : optimal risk allocation decision support model

    Creator:
    Alsalman, Ali Abdullah
    Abstract:
    It has been suggested that projects in the construction industry are subject to risks more than other industries. However, there is often little parity in allocation of risks in the construction industry. Usually, project participants allocate risks by aversion where owners tend to shift risks to the primary contractor, who...

  • Engineering design and analysis of pipe ramming installations

    Creator:
    Meskele, Tadesse
    Abstract:
    The trenchless technology known as pipe ramming for construction of culverts and buried pipes under roadways or other infrastructure has gained significant popularity due to its cost-effectiveness and ability to alleviate surface disruptions associated with open-cut trenching. Although the experience with pipe ramming is increasing, there has been remarkably little...

  • Shrinkage study of high performance concrete for bridge decks

    Creator:
    Fu, Tengfei
    Abstract:
    In the field of civil infrastructure, bridge desks are typically constructed using high performance concrete (HPC). Concrete bridge decks demand qualities such as low permeability, high abrasion resistance, superior durability, and long design life. Over decades of field and laboratory experience, many HPC bridge decks have been found to be...

  • The seismic geotechnical modeling, performance, and analysis of pile-supported wharves

    Creator:
    McCullough, Nason J.
    Abstract:
    This dissertation presents the results of a research effort conducted to better understand the seismic performance and analysis of pile-supported wharves. Given the limited number of well-documented field case histories, the seismic performance of pile-supported wharves has been poorly quantified, and the analysis methods commonly employed in engineering practice have...

    Creator:
    Bonell, John Alexander
    Abstract:
    Expansive soils in Eugene, Oregon present a problem to residents, consultants, contractors, and the city government. During the years 1977 to 1979, the nature and extent of the problem was identified, including an outline of the local occurrence of expansive soils and possible engineering solutions to the most often encountered...

  • Evaluation of Driver Behavior during Right Turn Maneuvers at Signalized Intersections: Mitigation of Driver-Pedestrian Conflicts with a Right Turn Flashing Yellow Arrow

    Creator:
    Jashami, Hisham
    Abstract:
    Accommodating motor vehicles that are turning (left or right) at signalized intersections requires a careful understanding of the safety and efficiency of design and operational variables. Turning vehicles are the primary collision risk for non-motorized road users at signalized intersections. When turning movements need to be controlled, proper driver response...

    Creator:
    Adams, Matthew P.
    Abstract:
    Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...

    Abstract:
    Reflection of an obliquely incident solitary wave at a vertical wall is studied experimentally in the laboratory wave tank. Precision measurements of water-surface variations are achieved with the aid of laser-induced fluorescent (LIF) technique and detailed temporal and spatial features of the Mach reflection are captured. During the development stage...

  • Review of guidelines for the design of tsunami vertical evacuation buildings

    Creator:
    Cawley, Jessica Grace
    Abstract:
    Tsunamis have the potential to inflict severe damage and loss of life in coastal communities. Structures known as vertical evacuation buildings provide an alternative evacuation site for communities living in relatively flat, coastal regions with inadequate sources of high ground for evacuation. Design of these structures balances risk and economy,...

  • Dual Purpose Utilization of Titanium Alloy Bars for Impressed Current Cathodic Protection and Near Surface Mounted Retrofit in Reinforced Concrete Beams

    Creator:
    Slawinski, Amanda K.
    Abstract:
    Many older reinforced concrete bridges and buildings in the United States are considered deficient due to past design codes that are not conservative, increased loading, and deterioration of structural components. Deterioration is most commonly caused by corrosion, which reduces the steel cross sectional area and damages the concrete cross section....

    Abstract:
    An understanding of natural coastal hazards is essential for improving resilience of coastal communities. Effective management of coastal hazards relies on prediction tools and mitigation structures that have been designed to handle the dynamic coastal system.

    Abstract:
    Degradation of watersheds is a major concern in areas where adverse climate effects and unsustainable use of the natural resources have caused extensive stresses to watershed systems (e.g., increased floods, increased droughts, worsened in-stream water quality) through the years. While considerable efforts are being made to generate technical solutions that...

  • Ultimate bearing capacity of shallow footings on plastic silt

    Creator:
    Newton, Vernon C.
    Abstract:
    The usual approach to calculation of the ultimate bearing capacity of plastic silt is to assume no porewater drainage occurs during the loading period. The coefficient of permeability of plastic silt is generally significantly larger than clay; therefore, partial drainage of porewater may occur during the loading period. This study...

    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...

    Engleson, Renee M.
    Abstract:
    Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...
