CONTINUOUS RANDOM WAVE LOADING ON STRUCTURAL MEMBERS
This paper considers the short-term probabilistic description of random wave loading on offshore structures composed of members for which the Morison form of load mechanism is appropriate. Special consideration is given to dealing with the inherent nonlinearity of the drag forces. The general multivariate distribution of loading is derived from the linear Gaussian model of long-crested random seas. The application of the multivariate distribution to yield the probabilistic description of structural response variables is indicated. Probability distributions of peak loads are developed which show the general wideband behavior contrasted with the simpler distribution which results from appropriate narrow band assumptions. Comparisons of the theoretical models are made with prototype recordings from an offshore platform and laboratory scale experiments.
