  • Prediction models for creep behavior of nailed joints between Douglas-fir lumber and plywood

    Creator:
    Jang, Sangsik
    Abstract:
    To apply accurate procedures of structural analysis that are now available, the behavior of nailed joints in light-frame wood buildings under long-term loads needs to be studied. Such a behavior can best be evaluated by testing specimens under constant loads, which requires relatively simple testing arrangements. To provide for a...

  • 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...

  • Design, analysis and evaluation of bridge superstructures for live loads

    Creator:
    Turan, O. Tugrul
    Abstract:
    Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...
