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.

Below
you can download an AVI
movie showing two
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.
