Abstract: |
This paper describes some studies relating to structural health monitoring techniques based on vibration measurement using laser Doppler vibrometer (LDV) and MEMS based sensor. 1) Compact and portable LDV measurement system was developed and applied to tensile force measurement of cables in a cable-stayed bridge. 2) The system combining LDV with Total Station was developed for the purpose of automated remote measurement for whole large bridge. 3) A new wireless LAN accelerometer based on MEMS technology was evaluated and applied to field measurement of bridges. |
