  • Finite element modeling of gusset plate failure using OpenSees

    Creator:
    Walker, Andrew J.
    Abstract:
    The collapse of the I-35W Bridge in Minneapolis, MN in 2007 prompted an investigation into the design and inspection of the steel truss bridges. Further investigation into the collapse revealed that a gusset plate experienced sway buckling, causing the bridge failure. This bridge failure motivated research into the analysis and...

  • Petroleum refinery residuals : a recycling feasibility study

    Creator:
    Hoffman, Andrew J.
    Abstract:
    Large quantities of unused heavy oil and residual waste products from the petroleum refining industry were deposited in on-site landfills, pits, and lagoons, prior to the promulgation of regulations governing their disposal and technology development that would further utilize and/or recycle these materials. Contacting petroleum products with sulfuric acid for...

  • Quantification of advection and dispersion in lateral subsurface flowpaths at the hillslope-scale

    Creator:
    Victory, Nichole I.
    Abstract:
    It is becoming increasingly important to understand fundamental hillslope-scale hydrological processes. Most hillslope-sale transport experiments have generally focused on conceptual findings or other aspect of flow behavior, rather than the quantification of the mass transport mechanisms of advection and dispersion. When the velocities have been quantified, dispersion has been mentioned...

  • Three dimensional dynamic video position sensing

    Creator:
    Jansky, L. Andrew
    Abstract:
    A comprehensive system to locate and track objects in two or three dimensional space, using non-contact video sensing techniques is described. The need exists to be able to quantify range and proximity of objects that would be difficult or impossible to measure using standard contact based sensor technology. Available video...

  • Bearing capacity and immediate settlement of shallow foundations on clay

    Creator:
    Strahler, Andrew W.
    Abstract:
    Shallow foundations are extensively used to support structures of all sizes and derive their support from near surface soils. Thus, they are typically embedded up to a few meters into the soil profile. Designers of shallow foundations are required to meet two limit states: overall failure of the soil beneath...

  • A study of the coagulation of kraft effluent by sea water

    Creator:
    Andrews, Ben Neal
    Abstract:
    The coagulation of effluent from the kraft pulping and papermaking process was investigated. The amount of material coagulated from saline mixtures of the effluent is determined as a function of time, salinity, kraft effluent concentration, and mixture pH. Individual sources of salinity include sea water and several different solutions of...

  • Lidar-based Post-earthquake Pavement Damage Classification System

    Creator:
    Shakya, Suzanna
    Abstract:
    3D laser scanning has been used extensively in engineering reconnaissance surveys to capture perishable data in an efficient, reliable, and precise manner. Many insights on damage can be obtained from the data through various methods of post-processing; however, many of these techniques are often labor intensive. This delay reduces the...

  • Wind induced torsional fatigue behavior of truss bridge verticals

    Creator:
    Keller, Philipp
    Abstract:
    The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...

  • Evaluating Worker Performance Using the Energy Concept

    Creator:
    Alotaibi, Abdulaziz M.
    Abstract:
    Over the decades, worker performance on construction projects has been a significant source of concern to be evaluated. Comprehensive studies have developed models for evaluating worker performance outside of the construction industry; however, minimal research has been conducted to evaluate worker performance in the construction industry. One of the reasons...

  • Near-Surface Response of Beach Sand : An Experimental Investigation

    Creator:
    Adams, Rachel Katie
    Abstract:
    The near-surface region of a coastal sediment bed is complex and dynamic. At some sites, near-surface sediment deposits are susceptible to extreme events, such as tsunamis or other large overflows, which induce high shear stresses on the sediment bed. The specific properties of sediment beds subjected to such extreme loading...
