Note on Structural Loads Analysis in the Reliability Context.

摘要

In order to fully exploit reliability based structural design methods in the design of naval vessels, means to analytically predict the magnitude and distribution of wave induced and slamming loads must be developed in a form which is consistent with the requirements of both the structural designer and the reliability analyst. This requirement defined the objectives of the present exploratory development task in hydrodynamic loads. A first step in this task was to assess the framework within which the products of this task should fit in order to insure the desired consistency with the other parts of the problem. The present document summarizes an initial attempt to define such a framework. It includes a review of modern reliability methods from the point of view of the load analyst, some thoughts on a practical strategy of meeting the perceived needs with state-of-art technology, and a discussion of a few issues which, according to the literature, appear not to have been completely resolved.
