  • The seismic vulnerability of sheet pile walls

    Creator:
    McCullough, Nason J.
    Abstract:
    The seismic performance of port structures has been well documented following recent earthquakes, and indicates that port structures are highly susceptible to earthquake-induced damages. These damages are primarily due to soil liquefaction and the associated ground failures. Sheet pile bulkheads provide vital intermodal and lifeline transportation links between water-side and...

  • Evaluation and application of ice segregation parameters for frost heave prediction

    Creator:
    Ito, Yuzuru, 1958-
    Abstract:
    The success of civil engineering construction in cold regions often depends on the assessment of the potential for frost heave. Over the past two decades two models have been presented to the engineering community to identify the frost heave potential, namely: (1) the segregation potential (SP), and (2) the discrete...

  • Stochastic analysis of a nonlinear ocean structural system

    Creator:
    Lin, Huan
    Abstract:
    Stochastic analysis procedures have been recently applied to analyze nonlinear dynamical systems. In this study, nonlinear responses, stochastic and/or chaotic, are examined and interpreted from a probabilistic perspective. A multi-point-moored ocean structural system under regular and irregular wave excitations is analytically examined via a generalized stochastic Melnikov function and Markov...

  • Nonlinear oscillations, bifurcations and chaos in ocean mooring systems

    Creator:
    Gottlieb, Oded
    Abstract:
    Complex nonlinear and chaotic responses have been recently observed in various compliant ocean systems. These systems are characterized by a nonlinear mooring restoring force and a coupled fluid-structure interaction exciting force. A general class of ocean mooring system models is formulated by incorporating a variable mooring configuration and the exact...

  • Chaotic response and stability of offshore equipment

    Creator:
    Lin, Huan
    Abstract:
    This investigation deals with the chaotic rocking response and overturning stability of offshore equipment subjected to base excitations due to wave-induced motions of the supporting compliant offshore structural system. The equipment compliant structural system is modelled as a free-standing rigid object subjected to horizontal and vertical base accelerations. Three of...

  • Stochastic analysis of complex nonlinear system response under narrowband excitations

    Creator:
    Shih, I-Ming
    Abstract:
    Response behavior of a nonlinear structural system subject to environmental loadings is investigated in this study. The system contains a nonlinear restoring force due to large geometric displacement. The external excitation is modeled as a narrowband stochastic process possessing dynamic characteristics of typical environmental loadings. A semi-analytical method is developed...

  • Deterministic and stochastic behaviors of a piecewise-linear system

    Creator:
    Mha, Ho-Seong
    Abstract:
    The (nonlinear) response behavior of a piecewise-linear system is investigated under both deterministic and stochastic excitations in this study. A semi-analytical procedure is developed to predict the system behavior by evaluating the joint probability density functions of the Fokker-Planck equations of the stochastic piecewise-linear system under random excitations via a...

  • Deformation-based seismic design models for waterfront structures

    Creator:
    Yang, Dong-Shan
    Abstract:
    Recent experience demonstrates that waterfront structures are vulnerable to earthquake damage. The poor seismic performance of these facilities has been primarily due to liquefaction of backfill and/or foundation soils and the lack of seismic design standards for waterfront structures. The seismic performance of waterfront structures is a key issue in...
