持続型耐震構造学研究室(Sustainable Earthquake Resistant Structure)-松尾准教授
阪神・淡路大震災以降，建物の継続使用・早期復旧などの重要性が再認識され，建築構造の研究対象も多方面へ展開されています．当研究室では，その一つの研究対象として鋼構造およびコンクリート充填鋼管（CFT）構造の接合部を中心に研究を進めています．力学的合理性を追求するのは当然ですが，施工性・経済性・持続性等における優位性も同時に求められます．このような様々な条件を満足できるより優れた接合部の開発，あるいは既存の接合部のより合理的な設計手法の開発を，研究テーマの中心に位置付けています．
一方，近年，様々な高強度材料が開発されていますが，それに伴って部材・接合部には更に高い耐力が要求される傾向にあります．したがって，既存の確立された接合技術（溶接・高力ボルト）による対応策，さらには既存の接合技術にとらわれない新たな技術の開発にも取り組んでいます．
本年度の当研究室メンバーは，博士後期1年生1名，修士2年生5名，修士1年生3名，学部4年生3名の総勢12名であり，日々，構造実験・解析等に取り組んでいます．添付の写真は，昨年秋～今年初めにかけて実施した伊都キャンパスでの構造実験写真です．
After the Great Hanshin-Awaji Earthquake, the importance of continued use and early restoration of damaged buildings has been reconfirmed, and research subjects of building structure have been expanded to various fields. Our laboratory is mainly conducting research on connections of steel structure and concrete filled steel tubular (CFT) structure. Although it is natural to pursue mechanical rationality, superiority in construction efficiency, economic efficiency, sustainability etc. is also required at the same time. We are positioning the development of better connections that can satisfy such various conditions or the development of more rational design method of existing connections as the center of research theme.
On the other hand, since various high-strength materials have been developed in recent years, higher strength tends to be required for members/connections. Therefore, we are also working on developing countermeasures based on the existing established joining technology (welding/high-strength bolts) and developing new technologies not limited to existing joining technologies.
The members of our laboratory in this fiscal year are a total of 12 people, including 1 first year doctoral course student, 5 second year master’s course students, 3 first year master’s course students and 3 fourth year undergraduate students, and we are working on structural experiments and analysis every day. The attached photographs show the structural experiments conducted from the end of last year to the beginning of the year.
