Characterizing earthquake induced building damage in an efficient, automated and non-
invasive way is a crucial support for the decision on further usability of critical infras-
tructure. In the GIOTTO project (Gebäudeschwingungen: kombinierte Zustandsanalyse
mit innovativem Sensorkonzept) we propose to use 6 degrees of freedom sensors (6DoF)
to monitor the complete movement of a building structure in three rotational and three
translational degrees of freedom. On one side, we develop 6DoF sensor networks for
strong motion building monitoring on the basis of 20 inertial measurement units (IMU50
by iXblue, France) originally designed as north-finding gyroscopes, on the other side we
incorporate the new observable of rotational ground motions into the concept of coda wave
interferometry for continuous real-time structural health monitoring. In this contribution
we show first results (1) from laboratory experiments for sensor performance characteriza-
tion as well as (2) from a 6DoF active source experiment at a horizontal 24 m long concrete
beam (the BLEIB test structure hosted by the Bundesanstalt für Materialforschung und
-prüfung, south of Berlin, Germany).
