Abstract
It can raise frictional force to install rubber mat between concrete blocks with the gravity style stacking structure such as concrete lump block and build upright wave absorbing block. Using rubber mat, the authors suggested a method to improving the earthquake resistance of the structure stacking up blocks. The authors prepared the model of installed the rubber mat between the concrete blocks, and experimented on the vibration for the inspection of the suggestion method. The rubber mat prepared for different five kinds of the hardness. The rubber mat performed a coefficient of friction examination and measured a coefficient of static friction and a dynamic friction. By the result of those experiments, the authors clarified the characteristics of the vibration when rubber mat was installed and were able to confirm the effectiveness of the rubber mat which could improve the earthquake resistance.
