Abstract:

The long-term goal of the research is to develop a unified, systematic, reliability-based analysis and design methodology for nonlinear, dynamically sensitive ocean structural systems incorporating the influence of a full range of possible motions. The transition phenomena among various complex nonlinear motions including periodic, quasi-periodic, chaotic, noisy periodic, noisy chaotic and purely random responses, and their effects on extreme excursions and fatigue behavior of structural systems will be emphasized. The immediate objectives are 1 to analyze the measured data of a medium-scale experiment conducted at the OSU Wave Research Laboratory on the dynamic responses of a nonlinear moored system 2 to calibrate the predictive capabilities of the analytical models developed under this research project using the experimental results and 3 to study the transition phenomena among various types of response motions via the parameter maps constructed from the experimental results complemented with analytical predictions.
