The aim of the test was to evaluate the behavior of
the perimeter walls toward inside (courtyard) and
outside (ditch) the fortress, after the overturning
mechanisms activated by the earthquake. From a
structural point of view it was important to know if the
two walls (also thanks to the provisional tie-rods
system) have different dynamic behavior after the
seismic event.

SETUP 3
In order to maximize the amplitude of the signals, the
accelerometers - in the considered setup - were
positioned on the upper floors of the building (first
and second floor).
PROSPETTO-SEZIONE BB'
Five configuration setups were performed with 27
points of acquisition. For each setup no more than
eight sensors were used, including two fixed reference
sensors, arranged in two directions (X and Y) parallel
to the ground and perpendicular to each other
(channels 1 and 2 at the second floor)
