Chaotic and Random Responses of Ocean Structural Systems

Abstract

The long-term goals of the research project were to develop a systematic analysis and design procedure for nonlinear ocean structural systems unifying both the deterministic and stochastic approaches. The procedure would provide a basis for: (1) analyzing the system response to combined periodic and stochastic excitations, (2) estimating the likelihood of chaotic response and developing guidelines for field observations, (3) predicting long-term extreme values of chaotic and stochastic responses based on measured data, and (4) ultimately, developing design methods to take into account both chaotic and stochastic behavior of compliant ocean systems. The near-term goals for the research were first to develop and analyze basic nonlinear ocean system models to understand their deterministic chaotic behavior, and then to extend the basic models to include stochastic aspects. Efforts focused on: (1) developing analytical models of compliant structural systems to understand the physics of chaotic behavior, (2) determining the existence and range of chaotic response of compliant structural systems under combined periodic and stochastic excitations; and (3) validating analytical results experimentally.
