| 要旨 | Major recent consideration about method for conducting overall investigation on structures for damage evaluation is being considered and solved. The device and method being used and developed respectively are a combination between Laser Doppler Vibrometer that can capture ambient vibration information of a structure and Time-Domain System Identification Algorithm that can outcome stiffness values of it. By combining these approaches, the part-by-part regular damage investigation of other NDT techniques is replaced by an overall investigation. As a case, damage investigation on tunnel is presented and some proven abilities of the method are highlighted. |
