| Outline of Final Research Achievements |
In this study, an earthquake protection system for structures using rubber pads (Scrap Tire Pads: STP), which are manufactured by cutting, dividing, and laminating waste tires for automobiles, was investigated. This research aimed to elucidate the mechanical characteristics of STPs and verify the seismic response control effects when the proposed system was installed into building structures. A series of static and dynamic loading experiments were conducted on STP specimens to understand various characteristics in the vertical (compression) and horizontal (shear) directions. Furthermore, the control effects of the proposed system were numerically analyzed by seismic response simulations. From these, the mechanical properties of STP units were obtained and it showed that the proposed system would be generally effective for improving the earthquake resistance of structures.

本研究では、自動車用の廃タイヤを切断・分割・積層して製作されるゴムパッド（STP）を用いた構造物の高耐震化システムについて検討した。STPは、入手性・経済性・環境負荷の面で優れた材料である。STPは、世界各国で容易に調達可能な廃タイヤから製作でき、特殊な加工技術を必要としない。提案システムは、先進国はもちろん途上国でも低コストに適用できる耐震性向上技術になり得る可能性があり、廃材の活用による環境負荷低減への貢献という面でも意義があると期待している。
