Stochastic linearization of systems with hysteretic characteristics
Keywords:stochastic linearization, hysteretic characteristic, random excitation, Bouc-Wen model
In this paper is presented a linearization method for a stochastic differential system with hysteretic characteristics and random excitation. The Gaussian equivalent linearization technique is applied to a system with hysteretic characteristic modeled by a Bouc-Wen equation. In order to verify the efficiency of the linearization method, the standard deviations of the equivalent linear system response are compared with those of Bouc-Wen nonlinear system for two case studies: Gaussian white noise and seismic inputs.
