  • Seismic performance of a pile-supported container wharf structures in rockfill

    Creator:
    Kawamata, Yohsuke
    Abstract:
    Recently, the concept of performance based design has become popular for many types of structures, including port facilities under seismic loading. For the case of pile-supported wharves, the level of performance is generally estimated using the displacement capacity of the structure. Therefore, understanding soil-pile interaction is one of the most...

  • Behavior of a 1/6th scale, two-story, wood framed residential structure under surge wave loading

    Creator:
    Wilson, Jebediah
    Abstract:
    The goal of this study was to develop an understanding of the nature of surge wave loading on wood framed residential structures for a variety of building configurations and test conditions. The objectives of the study were: (1) to measure forces on a 1/6th scale wood framed residential structure, (2)...

  • 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....

  • A direct-drive wave energy converter with contactless force transmission system

    Creator:
    Agamloh, Emmanuel B.
    Abstract:
    Commonly proposed ocean wave energy converters (OWEC) use inefficient and maintenance demanding intermediate hydraulic and pneumatic systems. We propose a novel rotary direct-drive OWEC that eliminates these intermediate stages. The new device employs a contactless force transmission system (CFTS) comprising a “piston” and a “cylinder” and a ball screw to...

  • 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...

  • Level structure of ¹⁵²Gd populated in ¹⁵²Tb β decay

    Creator:
    Stapels, Christopher John
    Abstract:
    As part of a research program to study the transitional region of N=88 isotones, ¹⁵²Tb was produced by the reaction ¹⁵¹Eu(α,3n)¹⁵²Tb in the 88" cyclotron located at LBNL. Gamma-ray spectroscopy of the radiation emitted from excited ¹⁵²Gd following the β⁺ decay of ¹⁵²Tb has been performed using an array of...

  • 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...

  • A study of the characteristics of oscillatory surface instabilities leading to droplet formation

    Creator:
    Daniels, Brian J.
    Abstract:
    The characteristics of the free surface in an orifice driven by a periodic forcing function have been studied both theoretically and experimentally. In the theoretical study, two wall boundary condition cases were examined: 1) the radial velocity at the wall of the orifice is zero; and 2) the axial velocity...
