In a massvarying structure like an elevated station, the mass of the second story (the upper story) is much smaller than that of the first story (the lower story), and seismic force of the second story tends to increase significantly. If the mass of the second story is simply increased so as to adjust the mass ratio in the vertical direction, it would be necessary to redesign the entire structure. To adjust the mass ratio of the structure, application of inertial mass is presented in this paper. Inertial mass is the apparent mass in vibration phenomenon. Using this, it would be able to adjust the mass ratio of the structure during an earthquake without large increase in substantial mass. However the method of controlling seismic response of building using inertial mass has developed recently, there is no case of the application to mass-varying structure such as railway building. In view of this, the method of adjusting the mass ratio is presented. Through shaking table test and analysis, this study shows that the large seismic response of the second story is reduced by application of inertial mass installed in the second story only.
