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 5 people, including 1 doctoral course student, 3 master’s course students and 1 fourth year undergraduate students, and we are working on structural experiments and analysis every day. The attached photos show structural experiments conducted in recent years.
