Abstract
In this paper, in the case of stacking structure such as build upright wave absorbing block, we proposed a method for improving the earthquake resistance of the structure by installing a rubber mat between the concrete blocks. For the verification of the proposed method, we practiced the model experiment and the numerical analysis, and we confirmed effectiveness of the proposed method. First, we confirmed the vibration characteristics of the case with and without installation of the rubber mat from the experiment using the shaking table. Next, we determined the external force to collapse in the case of without installation rubber mat, and we confirmed effectiveness of the rubber mat placed in the same conditions. In addition, we carried out the numerical analysis for the experiments and confirmed the validity of the analysis measured the identification. As a result, we clarified the vibration characteristics in the case of with installation of the rubber mat and were able to confirm the beneficial effects of improving earthquake resistance.
