In this paper, essential dynamic behaviors of braced structures with deteriorating characteristics subjected to random excitation are described. It is assumed that the braced structure is a single-degree-freedom system. In the former part, transient and stationary responses of the braced structure subjected to stationary white excitation are solved by Monte Carlo technique, and its essential behaviors are discussed. In the latter part, hysteretic characteristics of the braced structure are approximately formulated on the basis of numerical results, and the stationary responses of the system are solved by equivalent lineapization technique. Its results are compared with simulated results, and general behaviors on the random response of the braced structure are discussed.
