An evaluation method for the residual performance of a supplemental facility on structures was proposed to quantify its recoverability after an earthquake. In this study, two indices were proposed. The one was Rr, expressing the amount of deterioration of the seismic performance after an earthquake. The other one was Rd that is the intensity ratio of second to first earthquake, assuming the structure endures under first motion but reaches its limit state under the second motion. The proposed indices were evaluated for an electric power pole on top of railway structure. It consequently follows that proposed methods would successfully help to determine the necessity of repair of power poles immediately after an earthquake.
