  • Deterministic and stochastic control of nonlinear oscillations in ocean structural systems

    Creator:
    King, Paul E.
    Abstract:
    Complex oscillations including chaotic motions have been identified in off-shore and submerged mooring systems characterized by nonlinear fluid-structure interactions and restoring forces. In this paper, a means of controlling these nonlinear oscillations is addressed. When applied, the controller is able to drive the system to periodic oscillations of arbitrary periodicity....

  • Numerical modeling of full-coupled fluid-structure interaction

    Creator:
    Yuk, Dongjun
    Abstract:
    A numerical model for the simulation of fully-coupled fluid-structure interaction is developed in this study. In modeling the fluid, the Reynolds Averaged Navier-Stokes equations are solved for an incompressible viscous fluid field and a k-ε model is employed for turbulence computations. Hydrodynamic forces obtained by the integration of the fluid...

  • The seismic geotechnical modeling, performance, and analysis of pile-supported wharves

    Creator:
    McCullough, Nason J.
    Abstract:
    This dissertation presents the results of a research effort conducted to better understand the seismic performance and analysis of pile-supported wharves. Given the limited number of well-documented field case histories, the seismic performance of pile-supported wharves has been poorly quantified, and the analysis methods commonly employed in engineering practice have...
