既存大規模木造建築物の耐震補強技術の開発[基盤]

摘要

At the time of a disaster, schools play a role of a local resident's emergency evacuation area. Moreover, schools are the places of the activity which children pass the greater part of the day. Therefore, reservation of the safety of the school building is very important, and promotion of earthquake-proofing is an important subject. The Special Measure Law on Earthquake Disaster Prevention was revised in June, 2008, a duty of seismic capacity evaluation was newly imposed upon the wood school building beyond the fixed scale built before 1980. Since there are very few technical data about the earthquake-proof element and seismic reinforcement technology of the existing large-scale wood building including a wooden school building, it is difficult to evaluate the earthquake-proof performance of the existing large-scale timber building. In order to evaluate appropriately the earthquake-proof performance of the existing large-scale wood buildings, this study aims at development of seismic reinforcement technology suitable for the existing large-scale wood building.%学校施設は、非常災害時には地域住民の応急避難場所としての役割を果たすと共に、子供たちがー日の大半を過ごす活動の場であることから、その安全性の確保は極めて重要であ、耐震化の推進が喫緊の課題となっている。2008年6月には地震防災対策特別措置法が改正され、これまで努力規定だった木造校舎のうち、昭和56年以前に建設された一定規模以上の校舎に耐震診断が新たに義務づけられた。
