JETTY DESIGN USING DUAL LIFE-CYCLE AND PHYSICAL MODELING APPROACH – COOS BAY, OR

The advantages of risk-based methodologies over traditional deterministic analyses have been well documented for the design of coastal projects. The consideration of probabilistic forcing allows for the application of a life-cycle approach that can be used to optimize structure design, including the quantification of uncertainty. Damage progression and functional performance can be assessed over the project’s design life and can be considered in the design process. A lifecycle modeling approach was developed and applied, in conjunction with a 1:55 scale physical model, to the design of the North jetty major maintenance repair in Coos Bay, Oregon.
