  • 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...

  • 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...
