  • Hydraulic functions of soils from physical experiments and their applications

    Creator:
    Su, Charles
    Abstract:
    Based upon the Pearson Type VIII distribution function, a general retention function which relates the saturation to the capillary pressure in disturbed soils has been discovered. This simple and yet complete function has been shown to describe precisely the imbibition as well as the drainage branch of the retention curve....

  • 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...

  • Coupled response of compliant offshore platforms

    Creator:
    Young, Raymond A.
    Abstract:
    A three dimensional finite element analysis is developed which is capable of simulating the coupled static and dynamic behavior of compliant ocean structures. Nonlinearities which result from large-deflection, reduced or zero stiffness in compression, and the nonconservative fluid loading are considered. The spatial variation of fluid loading is also addressed....

  • A composite-beam finite element for seismic analysis of wood-framed buildings

    Creator:
    Lee, Chyuan-shen
    Abstract:
    A computer program called SAPWOOD which possesses the capability of performing linear or nonlinear, static or dynamic response including seismic excitation for wood-framed buildings with semirigid connection systems is presented in this study. Program SAPWOOD is a modification of the program NONSAP by adding new elements such as a linkage...

  • Effects of an industrial fire on a community of south Phoenix, Arizona

    Creator:
    Degher, Alexandra B.
    Abstract:
    On August 31, 1992, Quality Printing Circuits, a circuit board manufacturing plant in Phoenix, Arizona, burned to the ground. The fire lasted approximately eight hours, creating a thick, black smoke that blew into the surrounding community. Emergency evacuation was erratic and since no air samples were taken during the fire,...

  • 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...

  • 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...

  • Seismic protection of flexible rotating machines using base isolators

    Creator:
    Su, Wen-Chyi
    Abstract:
    Base isolation is an alternative seismic design strategy in which the primary structures and their internal components are uncoupled from the potentially damaging horizontal components of an earthquake by base isolators which attenuate the transmission of horizontal acceleration into the system. Rotating machines are among the key internal components of...

  • 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...
