A statistical non linearization method is used to approximate systems modeled by the Bouc differential equationand excited by a Gaussian white noise external load. To this aim restricted potential models (RPM) are used, whichare suitable for an extended number of nonlinear problems as have been proved several times. Since the solution of RPMis known by the probabilistic point of view, all statistical characteristics can be derived at once with advantages by thecomputational point of view. Hence, this paper discusses the possibility to determine sets of parameters characterizing potentialmodels that are valid for describing a hysteretic behavior. In this way the characterization of the hysteretic behaviorof a system can be performed with computational efforts lower than that normally requested.
