  • Numerical response of concrete-lined tunnels crossing active faults

    Creator:
    Lange, Stephanie
    Abstract:
    A challenge for municipal authorities of growing urban areas is to provide larger and faster transportation and utility networks that are safe and resilient to significant disruptions after an earthquake event and other disasters. Urban regions, like the San Francisco Bay or the Los Angeles area, are situated in seismically...

  • 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...

  • Response Sensitivity Formulations for Geometrically Nonlinear Finite Element Analysis

    Creator:
    Al-Aukaily, Alabbas
    Abstract:
    Significant amounts of uncertainty owing to both modeling decisions and inherent randomness are present in simulating the material and geometric nonlinear response of structural systems to extreme loading. Computing the sensitivity of structural response with respect to model parameters indicates which parameters have the largest affect on the response, which...

  • 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...

  • 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%,...

  • Effects of soil slope on lateral capacity of piles in cohesive soils

    Creator:
    Nimityongskul, Nontapat
    Abstract:
    Pile supported bridges are typically constructed near or in a natural or man-made slope and are subjected to lateral loading. The current design method for laterally loaded piles involves the use of Winkler's spring concept with the standard nonlinear p-y curves. The available p-y curves were developed based on results...

  • 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...

  • Seismic performance of a pile-supported container wharf structures in rockfill

    Creator:
    Kawamata, Yohsuke
    Abstract:
    Recently, the concept of performance based design has become popular for many types of structures, including port facilities under seismic loading. For the case of pile-supported wharves, the level of performance is generally estimated using the displacement capacity of the structure. Therefore, understanding soil-pile interaction is one of the most...

  • Three-dimensional experiments and modeling of anisotropic clay

    Creator:
    Anantanasakul, Pongpipat
    Abstract:
    This dissertation presents the results of a research effort conducted to better understand the stress-strain, volume change, shear band formation, and strength characteristics of normally consolidated anisotropic clay under fully three-dimensional stress states. A series of consolidated drained true triaxial tests with a constant mean effective stress and constant Lode...

  • Shear reinforcement effects of discrete columns in liquefiable soils

    Creator:
    Rayamajhi, Deepak
    Abstract:
    Discrete columns, such as stone and soil-cement columns, are often used to improve the liquefaction resistance of loose sandy ground. In particular, stone columns are considered to increase resistance potential by densification, drainage, and reinforcement mechanisms. For silty soil, the shear stress reduction resulting from the reinforcing effect of stiffer...
