Operational Modal Analysis of a Canadian Dam
The measurements and analysis presented here are
performed by Professor Carlos Ventura, University of British Columbia,
Vancouver, Canada.
This case consider measurements conducted on a Canadian dam. The dam is 130
m long and 58 m high, and built in 1930. The measurements were conducted
using an 8-channel measurement system. The sensors were Kinemetrics
Episensor, forced balanced accelerometers. Modal analysis was conducted with
ARTeMIS Extractor Pro.
The mode
shown above has been estimated with
the Enhanced Frequency
Domain Decomposition
estimator available in
the ARTeMIS Extractor
Handy and ARTeMIS
Extractor Pro versions.
