RISK-BASED ANALYSIS AND DESIGN AGAINST WIND AND WAVES
This course surveys the probabilistic analysis and design of structures subjected to steady wind and/or waves. General topics of power spectra, transfer functions, and random vibration are introduced. Mechanics-based models of kinematics and loading are described across a number of structural concepts. Because these problems typically involve many load cycles, fatigue as well as ultimate loading is of concern; both are considered here.
Results are considered from a risk/reliability perspective. Analysis methods of greatest practical interest are shown, including FORM (first-order reliability methods). The corresponding inverse FORM approach is used to yield environmental contours, an increasingly popular way to display the site-specific environmental threat due to wind and waves. These results will be demonstrated through various case studies, including fixed and floating ocean structures, on- and offshore wind turbines, etc.
