Twelve high resolution (up to 4MPixel) Infrared Cameras have been used to measure accurate 3-D positions of hundred of markers placed on the structure during the seismic tests. The innovative monitoring technique allows measuring 3 axial absolute displacements with easy and fast test set-up, high accuracy and the possibility to link the 3D-motion time histories of the tracked markers with CAD drawings of the structure and validate the FE models in real time experimental data assimilation. The new monitoring system have been tested during a shaking table experiment on a masonry building representative of the historical houses still used for civil habitation in Italy. Moreover, optical fiber displacement sensors and Bragg Grating Sensors have been applied for static and dynamic strain data acquisition within an extensive experimental investigation on shaking table carried out for the TREMA project (Technologies for the Reduction of seismic Effects on Architectural Manu facts) on a new system for the seismic retrofit of R/C frames.
