Because of the use of the pillars with the structure, the center of gravity of the building is high and there is a danger of collapse or overturning, and since there is no buffer, the natural period of the building and the natural period of the earthquake are synchronized. The shaking was amplified, and there was a problem that the building was subjected to stress to break or damage.

The conventional seismic isolation support structure for elevated structures such as elevated roads and bridges uses integrally formed piers, elevated supports, etc., so that the combined occurrence of horizontal and vertical seismic intensities causes the Great Hanshin-Awaji Earthquake. In the case of the compound earthquake of the above, since there is no buffer part, the natural period of the elevated building and the natural period due to the earthquake are synchronized, and the sway is amplified.
