  • Vibrations of suspended cables

    Creator:
    Gale, John Gregg
    Abstract:
    The equations of motion of an elastic cable suspended in a viscous medium from two arbitrary points are derived. These are then linearized for the undamped, inextensible case, and it is found that the equations describing the in-plane motion of the cable are then independent of the equation describing the...

  • The static and dynamic analysis of discretely represented moorings and cables by numerical means

    Creator:
    Dominguez, Richard Frank
    Abstract:
    Computer oriented techniques and procedures are presented for the analysis of single and multiple cable systems. Application is made to a two-point mooring system influenced by surface and subsurface hydrodynamic loading. The effects of the various parameters are presented and the numerical method is compared to exact solutions obtained from...

  • Nonlinear dynamic analysis of cable and membrane structures

    Creator:
    Lo, Alain
    Abstract:
    The nonlinear dynamic analysis of cable and membrane structures is presented in this study. Attention is given to the nonlinearities arising from large displacements, from nonlinear stress-strain relationships and from nonconservative loadings. The finite element method is used to model the cables and membranes. Curvilinear geometries of the elements are...

  • Coupled dynamics of bouys and mooring tethers

    Creator:
    Idris, Krisnaldi
    Abstract:
    Time-domain models were developed to predict the response of a tethered buoy subject to hydrodynamic loadings. A coupled analysis of the interaction of a buoy and its mooring is included and three-dimensional response is assumed. External loadings include hydrodynamic forces, tethers tensions, wind loadings and the weight of both cable...

  • Numerical Simulation, Laboratory and Field Experiments, Analysis and Design of Wave Energy Converter and Mooring System

    Creator:
    Lou, Junhui
    Abstract:
    This dissertation studies the coupled fluid-structure interaction (FSI) of a wave energy converter (WEC) and evaluates the design of a WEC mooring system. The research is conducted in support of conceptual development, field test and performance evaluation of WECs as part of the mission of the Northwest National Marine Renewable...

  • Aseismic performance of a cable-stayed structure with decentralized H[infinity] control

    Creator:
    Chńg, Guan B.
    Abstract:
    The dissertation uses state-of-the-art structural engineering theories, in parallel with the modern and still-developing control theory of electrical engineering to mitigate the vibratory responses of a double-stayed bridge subjected to strong earthquake ground motions. First, a nonlinear finite element model of the double-stayed bridge subjected to non-uniform (multi-support) earthquake excitations...

  • Improving soil water determination in spatially variable field using fiber optic technology and Bayesian decision theory

    Creator:
    Sayde, Chadi
    Abstract:
    Achieving and maintaining sustainability in irrigated agriculture production in the era of rapidly increasing stress on our natural resources require, among other essential actions, optimum control and management of the applied water. Thus, a significant upgrade of the currently available soil water monitoring technologies is needed. The primary goal of...
