Modal Analysis of the Heritage Court Tower
The measurements and analysis presented here are
performed by Professor Carlos Ventura, University of British Columbia,
Vancouver, Canada.
The building considered here is the so-called Heritage Court Tower, which is
located in downtown Vancouver, British Columbia, Canada. It is a relatively
regular 15-storey reinforced concrete shear core building. The building is
located on top of an underground parking structure.
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.
Below you can download an AVI movie animating the
mode showed above. The mode has been estimated with one of the Stochastic
Subspace Identification estimators available in the ARTeMIS Extractor Pro
version.

different estimates of the same mode shape animated on top of each other.
This is one of the effective validation tools available in the ARTeMIS
Extractor.
