Abstract: A simple model of stationary nonnormal responses is proposed. Based on a Hermite series transformation of a normal process, the model requires knowledge of only limited, easily estimated response statistics (i.e., central ...

Abstract: Hermite moment models of nonlinear random vibration are formulated. These models use response moments (skewness, kurtosis, etc.) to form non‐Gaussian contributions, made orthogonal through a Hermite series. First‐yield and ...

Abstract: A general method is shown here to model wind loads and responses for reliability applications. This method characterizes the short-term loads and responses by a few summary statistics: specifically, ...

Abstract: The air gap response of a specific semisubmersible platform subjected to irregular waves is considered. Statistical analyses are performed on model test data for the absolute near-structure wave elevation, and these measured ...

Abstract: The air gap response of a specific semi-submersible platform subjected to irregular waves is considered. Detailed model tests for this structure are studied in depth. Using time-histories of ...

Abstract: This paper considers two distinct topics that arise in reliability-based wind turbine design. First, it illustrates how general probability models can be used to predict long-term design loads ...

Abstract: The probability of a first‐excursion failure under individual and combined loading is estimated. First‐order results and upper bounds are constructed from the probability density and mean upcrossing rate functions of each ...

Abstract: Efficient methods are described here to predict the stochastic accumulation of fatigue damage due to nonlinear ship loads that are produced in random seas. The stochastic analysis method, which ...

Abstract: Two separate studies are presented here that deal with analytical predictions of the air gap for floating structures. 1) To obtain an understanding of the importance of first and second-order ...
