We propose the method of the elevator operation control for the long-period ground motion using Earthquake Early Warning System (EEWS) and apply this method to the elevator operation control system of the 29-story building of Kogakuin University in the downtown Tokyo, Shinjuku, Japan.<br> First, we estimate the velocity of surface wave that travels through the crustal calculated by the theoretical method, and we estimate the long-period ground motion by Green's function and calculate the lumped mass model response by the estimated long-period ground motion. Next we develop the trigger condition stopping the elevator based on above results. When EEWS is received, we reference the trigger condition and stop the elevator.<br> Next, we apply the elevator operation control for the long-period ground motion proposed method to Kogakuin University, which is high-rise building and located at the central of Tokyo. We compare the estimation the long-period ground motion by the wavenumber integration with the observation data. As a result, the estimated waves between 2 sec and 4 sec almost correspond the observed waves, but the estimated waves between 4 sec and 6 sec underestimate the observed waves because of the 3D effects of the Kanto sedimentary basin. Thus, we estimate the long-period ground motion to the estimation on the side of prudence given the assumption of the source model, because EEWS provides only the location and magnitude of an earthquake. We confirm that the proposed method is able to control the elevator for the long-period ground motion.
