• Basic equations of energy-tocth-power difference criterion were derived for multi-degreeof-freedom(MDOF) systems subjected to stationary Gaussian excitations with non-zero mean.Modal transform technique was used in order to reduce unknowns.Main computational formulae were presented and suggested values of c were given.Numerical results show that the method of this paper prevails over equation difference criterion both in accuracy and in simplicity.
