An equivalent wave system is defined as a simple sinusoidal wave, which is meant to be representative of a complex extreme load situation. The present paper discusses three different ways of selecting an Equivalent Wave System. The implications of the different hypotheses at the basis of the selection are discussed and the outcomes in terms of maximization of single responses and of combinations of different types of responses are analysed.

Abstract
An equivalent wave system is defined as a simple sinusoidal wave, which is meant to be representative of a complex extreme load situation. The present paper discusses three different ways of selecting an Equivalent Wave System. The implications of the different hypotheses at the basis of the selection are discussed and the outcomes in terms of maximization of single responses and of combinations of different types of responses are analysed. The extension of the concept of equivalent wave to fatigue life evaluations is also discussed, pointing out the different perspective from which a reference load situation is to be sought in this case.
