Research
In the Structural Analysis Laboratory, numerical analysis using computers is performed.
Calculating the behavior of structures contributes to the safety and security of society.
Our research focuses on computer-based numerical analysis (simulation). We closely track and evaluate how structures behave and their load-bearing capacity in response to natural disasters and external forces such as earthquakes, tsunamis, and collisions. We also focus on developing maintenance and management techniques to ensure the safe use of structures over the long term. Through cutting-edge analytical techniques, we contribute to the realization of a disaster-resistant, economically rational society.
Examples of research themes
Impact & Disaster prevention
In light of recent abnormal weather and global situations, there has been growing interest in impact problems. Tracking the destructive behavior of structures in response to impacts plays an important role from the perspectives of both protecting human lives and economical structural design. Therefore, the Structural Analysis Laboratory is developing analytical methods based on the finite element method and SPH method that can calculate advanced impact problems, and is conducting structural analyses using these analytical methods.
Maintenance
While the number of structures that have been in service for over 50 years is increasing, there is a shortage of personnel to manage these structures, and the development of new methods for managing these structures is required. The Structural Analysis Laboratory has been studying methods for detecting defects inside RC structures using hammering sound and thermography cameras. In recent years, we have been studying new defect detection methods using machine learning using accumulated hammering sound data.
General Structure
The number of aging infrastructure structures is increasing. Modern society is in the midst of a period of renewal, and proposals for more durable structures are required. By using numerical analysis techniques based on the finite element method to model these actual structures as much as possible and follow their behavior, we can clarify the strength of existing structures and demonstrate the validity of new structures, thereby contributing to the realization of an economical and sustainable society.
