Abstract— In recent years, urban disasters such as depleting groundwater and urban floods are increasing due to an increase in paved roads using asphalt and the like in Japan. As a countermeasure, rainwater storage and infiltration facilities (RSIF) that’s able to prevent flood by suppressing rainwater flowing into rivers and use the stored rainwater as domestic water by storing rainfall in the underground are being adopted in many cities. If these facilities are collapsed by earthquake motions, it is concerned that most buildings or people are affected by the damage. In order to prevent such a situation, it is desirable that RSIF has sufficient seismic resistant performance. In this study, the cyclic loading tests are conducted to investigate the seismic behavior and resistant mechanism. From the test results and observation record during loading test, a frictional behavior and the development of shear and bending load bearing mechanism were confirmed.
