  • 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...

  • Post-Earthquake Performance Assessment of Steel Strongback Braced Frames

    Creator:
    Rhoades, Katharine
    Abstract:
    Traditional braced frames are an efficient and economic means of resisting seismic demands. However, braced frames are prone to story mechanisms, which can result in concentrations of demands and damage during seismic events. Including steel strongbacks in conjunction with traditional braced frames can mitigate story mechanisms. The SBF results in...

  • Improving Braced Frame Modeling Application

    Creator:
    Groshong, Corey
    Abstract:
    This work analyzes the numerical curvature of buckling braces. An existing brace modeling learning tool, which in its current state allows users to change the inputs within a simulated model of a braced element, was modified to display the curvature diagram. The curvature diagram was verified through comparison to existing...

  • Flexural steel anchorage performance at diagonal crack locations

    Creator:
    Triska, Mary Ann
    Abstract:
    Large numbers of reinforced concrete deck girder bridges that were constructed during the interstate system expansion of the 1950s have developed diagonal cracking in the stems. Compared to the present AASHTO-LRFD standards, the provisions of the 1950s allowed for higher shear stress in the concrete, thus reducing the amount of...

  • 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...

  • Visualization and design systems for road infrastructure

    Creator:
    Esch, Gregory
    Abstract:
    Transportation infrastructure provides a vital service for the functionality of a city. The efficient design of road networks poses an interesting topic in computer science for digital content developers. For civil engineers, the visualization of analysis results on infrastructure both efficiently and intuitively is crucial. The following contributions are made...

  • Accuracy versus cost in distributed data mining

    Creator:
    Deutschman, Stephanie
    Abstract:
    A basic tradeoff to consider when designing a distributed data-mining framework is the need for a compromise between the cost of communication and computation resources and the accuracy of the mining results. This is essentially a decision of whether it is more efficient to communicate all of the data to...

  • Experimental research on the behavior and strength of large-scale steel gusset plates with sway-buckling response including effects of corrosion and retrofit options

    Creator:
    Hafner, Anthony G.
    Abstract:
    The collapse of the I-35W Bridge in Minneapolis, MN on August 1, 2007 brought into question the design and inspection of gusset plates in steel truss bridges. The experimental tests performed in this research study the sway-buckling strength and behavior of large-scale steel gusset plates in an isolated truss connection....

  • Behavior of open grid steel bridge decks under service and fatigue loads

    Creator:
    Fetzer, Peter C.
    Abstract:
    Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure continues to deteriorate, open grid decks can be used as a cost effective way to rehabilitate structurally deficient...

  • Optimization of Construction Equipment Efficiency and Cost using Simulation and Field Data

    Creator:
    Kumar, Deepak
    Abstract:
    Unlike other industries, overall efficiency of construction projects has been growing minimally which directly causes cost overruns of projects. Though reducing idle time and increasing operational efficiency of construction equipment could result in significant cost saving, there is lack of practical knowledge of adjusting operational efficiency and integrating cost and...
