ABSTRACT
Many engineering systems are subjected to loads that are random processes, e.g., random functions. The following are some examples: the wings of an airplane under gust loads, the hull of a ship under wave loads, and an offshore platform under wave loads. Moreover, the properties of many systems, such as their strength (stress at failure) are random and vary in time. The objectives of a random vibration study are to determine the statistics of the response of a system and the probability of failure due to the response. Tools for time invariant reliability problems, such as FORM and SORM, are not directly applicable to random vibration analysis.
