A method is described for estimating the number of elevators that have shut down after a large earthquake. In this method, the earthquake ground motion records obtained by a ground motion monitoring network are used to classify the ground motion distribution patterns, and the shutdown records in the maintenance database are used to obtain seismic-shutdown-ratio curves. The ground motion of the target earthquake is estimated using the ground motion distribution patterns, and the number of elevators that have shut down is then calculated using the seismic-shutdown-ratio curves. This method was verified using data from an actual earthquake of JMA seismic intensity 5 that occurred in the Tokyo area. In this verification, the estimated total number and distribution of elevators that have shut down matched well to the actual number and distribution. This estimation method could be used to speed up the process of restoring elevators that have shut down due to a large earthquake.
