Abstract
Stochastic linearization technique, widely used for analysis of nonlinear dynamic systems subjected to random excitations, is revisited. It is shown that the standard procedure that is universally adopted for determining of so called effective stiffness of the equivalent linear system, is erroneous in all previous publications. Two error-free stochastic linearization techniques are elucidated, namely those based on (1) the force linearization, and (2) energy linearization.
