  • A linkage finite element for nailed composite wood I-Beams and T-Beams

    Creator:
    Lee, Chyuan-shen
    Abstract:
    With current nonlinear analysis computer capabilities, this study was conducted to develop a linkage element that permits analyses of wood composite structures taking into account possible slip in the nailed joints. The finite elements chosen to represent the wood stud, plywood, gypsum and nails are described. The method as applied...

  • Irregular points in wavemaker boundary value problem

    Creator:
    Tanaka, Yoshihiro
    Abstract:
    A global solution is presented that accurately accounts for the singular behavior at all irregular points. The linearized boundary value problem in a semi-infinite strip in the physical plane is transformed into a smooth unit disk by two successive conformal mappings. The global solution results from a Fredholm integral equation...

  • Mass transport in laboratory water wave flumes

    Creator:
    Kim, Tae In
    Abstract:
    A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

  • Finite element analysis of wave interference effects between large structures

    Creator:
    Huang, Min-chih
    Abstract:
    A numerical calculation procedure for the hydrodynamic interference effects between large multiple structures interacting with linear ocean waves is presented in this study. Viscous effects are neglected and the hydrodynamic pressure forces are assumed to be inertially dominated. A finite element method which incorporates radiation boundary dampers is adopted to...

  • Determination of structural layer properties of aggregate and asphalt surfaced roads

    Creator:
    Rwebangira, T.
    Abstract:
    This study involved the determination of the structural layer properties of aggregate and asphalt surfaced pavements for use in the evaluation of pavement load carrying capacity and the seasonal effects of moisture. This was achieved by the use of Nondestructive Testing Methods (NDT) and backcalculation techniques. Pavement surface deflection measurements...

  • Finite element analysis of wave-structure interactions in the time domain

    Creator:
    Lee, Jaw-fang
    Abstract:
    The time-domain simulation of wave-structure interactions using the finite element method is presented in this study. Combined initial and boundary value problems for diffraction and radiation of waves by large structures are posed. Linearized free surface boundary conditions are used, but motions of the structural boundaries compared to the wave...

  • 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...

  • Cable dynamics in an ocean environment

    Creator:
    Tuah, Hang
    Abstract:
    The nonlinear dynamic analysis of cable and cable-large body systems subject to both deterministic and non-deterministic loading is presented in this study. Nonlinearities occur due to large displacements, material nonlinearity, lack of stiffness in compression, and the non-conservative fluid loading. A finite element model is used to model the cable...
