Abstract:

Corrosion of steel is an important factor in the design of marine structures. A reliability analysis of anchored bulkheads showed that corrosion changes the critical failure mode from kickout to serviceability failure of the steel sheeting. Because of this change in the failure mode over time, the design of a bulkhead subjected to corrosion requires consideration of multiple failure modes and the analysis of the bulkhead reliability over time. For design of bulkheads including corrosion, one must insure that corrosion does not trigger a collapse failure. A model has been developed which can determine the relative probabilities of a collapse versus a serviceability failure.
