In this investigation a new method for computing the first and second moments of the displacement response of linear elastic structures with random stiffness and damping is developed. The method accurately computes the mean and variance of the displacement of a dynamically loaded structure as functions of time. The probability that the displacement will be greater than a specified value is also computed. The results of the transformation method are compared to exact solutions for a number of cases. The influence of the randomness in the underlying parameters on the randomness of the response is discussed.
