  • 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...

  • Bridge Model Parameter Sensitivity in Pushover and Nonlinear Time History Analysis

    Creator:
    Johnsohn, Karryn E.
    Abstract:
    The aim of this research is to understand and quantify the modeling differences between CSiBridge and OpenSees, and to determine sensitive model parameters. When designing bridges for the high seismic region of California, the California Department of Transportation (Caltrans) performs nonlinear time history analysis of their bridge models. For three-dimensional...

  • 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...

  • 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...

  • Predicting pore pressure response in in-situ liquefaction studies using controlled blasting

    Creator:
    Eller, James Michael
    Abstract:
    Originally used as a method to densify loose soils, controlled blasting has expanded its applicability to geotechnical engineering by becoming a research tool to physically generate liquefaction for full-scale in-situ tests, ranging from seismic performance of deep foundations to evaluating ground improvement techniques. Current methods used to design the blasting...

  • 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...

  • Effects of soil slope on the lateral capacity of piles in cohesionless soils

    Creator:
    Barker, Paul D.
    Abstract:
    Deep foundations, including driven piles, are used to support vertical loads of structures and applied lateral forces. Many pile supported structures, including bridges, are subjected to large lateral loads in the form of wind, wave, seismic, and traffic impact loads. In many practical situations, structures subjected to lateral loading are...

  • Optimizing the performance of gypsum wall board in wood frame shear walls

    Creator:
    Goodall, Scott I.
    Abstract:
    The overall goal of this project was to design a wood frame shear wall that could withstand greater displacement before damage occurred to the Gypsum Wall Board (GWB). More specifically, the objectives of the study were: (1) to evaluate damage to the GWB in alternative shear wall designs at 1%,...

  • Computerized safety analysis technique for secondary highways

    Creator:
    Nichols, Kevin Scott
    Abstract:
    Evaluation of the safety hazards along a highway is usually performed at specific locations and on known hazards. But, it is also important to find any unrecognized hazards and their locations. Many factors contribute to accident potential, and the combined effect of several of them could produce a hazard that...

  • Use of benthic sediments as indicators of marina flushing

    Creator:
    Noble, Scott Morgan
    Abstract:
    This report presents the findings of a sediment analysis program formulated to determine the flushing potential of various shaped small boat marina basins. Chemical tests regarding volatile solids, Kjeldahl nitrogen, grease and oil, and sulfides were performed with the results compared to established sediment quality criteria. These results were used...
