The techniques considered in the extensive experimental programme carried out at the Seismic Laboratory of ENEA Casaccia (Rome) are based on i) a seismic isolation system realized by Added Damping Rubber Isolators devices (ADRI) and ii) on a new Active Confinement of Masonry strengthening system (CAM) consisting in a three-dimensional tie system for the upgrading of existing masonry structures. Towards this aim, two identical 3D masonry 1:1.5 scaled models have been designed and constructed in accordance with traditional construction codes of practice for the Italian Central and Southern Appenine Zones. Dynamic shaking table tests have been carried out applying a natural input (the 1997 Colfiorito earthquake) with increasing intensity. In addition, random tests have been performed before dynamic tests in order to verify model frequency decay and damage propagation on structural elements. The first model, previously strengthened by means of the CAM system, has been firstly tested in a base isolated configuration. Successively, the same model has been fixed at the base and then tested again in order to verify the effectiveness of the CAM system. The second model has been tested in fixed base configuration up to the failure condition. In this work the early results of the experimental tests carried out on the two models are illustrated.
