Abstract:

The following two topics are introduced as new methods for infrastructure monitoring:

Magnetic sensor
Magnetic sensor is used for non-destructive measurement of stresses of steel surfaces. Application examples are introduced for stress measurements for H-beam used for tunnels and ground anchors.


Light Emitting Deformation Sensor
Light Emitting Deformation Sensor is introduced as a key tool for infrastructure monitoring. The use of this new device enables real-time data processing and visualization on-site, so that the state of deformation for a structure in concern can be visually identified not only by engineers but also by citizens.

Biography:

Professor Shinichi Akutagawa has studied in Japan, USA, and Australia obtaining his Ph.D. from the University of Queensland in1991, in the field of back analysis for underground excavation problem. Since 2001, he has been working on non-destructive stress measurements of steel structures using the �Magnetic Sensor�. Also, he has been working on developing a new concept of infrastructure monitoring using �Light Emitting Deformation Sensor� to establish safer working and living environment.
