  • Investigation of Multi-constellation RTK GNSS Survey Productivity and Coordinate Accuracy

    Creator:
    Jamieson, Marian H.
    Abstract:
    This study evaluates the productivity and accuracy of surveys completed with single-base real-time kinematic (RTK) Global Navigation Satellite Systems (GNSS) using four different GNSS constellation combinations: (1) GPS-only, (2) GPS+GLONASS, (3) GPS+Galileo+BeiDou, and (4) GPS+GLONASS+Galileo+BeiDou. For this comparison, we set up a test site consisting of 20 stations ranging with...

  • Finite element modeling of reinforced concrete bridge columns with steel jackets using plastic hinge integration

    Creator:
    Carlton, Adam K.
    Abstract:
    In recent years confinement requirements for concrete columns have increased in seismic regions. Steel jackets are one way to confine reinforced concrete columns. The increased confinement provides additional strength and ductility for the columns during seismic events. For reinforced concrete columns with steel jackets, there are different section properties in...

  • Analysis of moving loads using force-based finite elements

    Creator:
    Kidarsa, Adrian
    Abstract:
    An analysis method for moving loads computes the internal demand history in a structural member at integration points of force-based finite elements as opposed to the end forces of a refined displacement-based finite element mesh. The force-based formulation satisfies strong equilibrium of internal section forces with the element end forces...

  • 3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

    Creator:
    Scoggins, Luke A.
    Abstract:
    A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

  • Fluid-structure interaction analysis with the particle finite element method

    Creator:
    Zhu, Minjie
    Abstract:
    To facilitate the evaluation and design of structures subjected to fluid loading, a study of fluid-structure interaction (FSI) using the particle finite element method (PFEM) is presented to approximate the responses and sensitivities of structures which interact with fluid. A wide range of structural types are permissible by making no...

  • Tsunami Loading on Coastal Infrastructure

    Creator:
    Xie, Zhongliang
    Abstract:
    The safety of coastal infrastructure has been a concern after the Indian Ocean Tsunami in 2004 and the Great East Japan Tsunami in 2011. The western coast of the United States is also exposed to tsunami hazards due to the Cascadia subduction zone. Therefore, it is critical to design coastal...

  • Tsunami Simulation Using OpenSees : Validation of Bridge Response and Exploration of Shallow Water Flow

    Creator:
    Cressman, Luke R.
    Abstract:
    The finite element software framework, OpenSees, has been used by researchers to simulate the response of structural and geotechnical systems to earthquake loading. Implementation of the Particle Finite Element Method (PFEM) has made it possible to simulate hydrodynamic forces through fluid-structure interaction (FSI) in OpenSees. To validate the FSI implementation...

  • Parametric uncertainties in reliability analysis of bridge structures

    Creator:
    Hamutcuoglu, Osman Murat
    Abstract:
    Probability-based reliability methods have placed an increased emphasis on realistic simulation of structural behavior in bridge engineering. Uncertainty is present in every aspect of structural analysis. Aleatory uncertainties in the loading and load-carrying capacities, and epistemic uncertainties in mathematical idealization of bridge systems are the major contributors to uncertain structural...

  • 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...
