This paper shows the reproducibility and stability of the effect of reducing seismic-response acceleration in the ancient substructures with numerous basket-shaped relics with rubbles filled, called shicras to gain deeper insight into the engineering significance of ancient building techniques used about 3,500 to 5,000 years ago. The shaking table tests showed a mechanism that spherical shicras started to rotate when the seismic-response acceleration level exceeded the given value, possibly enabling the effects of reducing seismic-response acceleration to be achieved.
