A perturbation method is widely used for the response analysis of structures with uncertain properties. Most of studies using a perturbation method, however, treat only the case of static or stationary responses. This paper presents a new procedure to evaluate the non-stationary structural response using a perturbation method. The external loads, such as earthquake ground motions, are modeled as non-stationary white random noises, and the structural properties, such as the mass, the stiffness and the damping coefficient etc., are also modeled as random variables. By applying this method, a three-stories RC-frame subjected to a random earthquake motion is analyzed. The results are compared with those of the Monte-Carlo simulations to examine the accuracy of this method.
