Abstract: A nonstationary random excitation which acts upon a structural system is considered. A simply one degree-freedom structural system with that excitation is analyzed by using a covariance equation method. Numerically calculating, the basic covariance equations are presented. A nonstationary response is easily calculated with a covariance equation method as compare with an integrated method and this method can extend to the some nonstationary problems. The numerically calculations are paformed to two examples which use the unite-step-function for the shape functions and the two sets of results appear to be in close agreement the most part. At last, using covariance equation, a mean square respose for a shape function is half-sinfunction is calculated.
