The aim of this work is to present the results of several laboratory tests conducted by the RITAM (University of Perugia's laboratory), on Emmedue System characterized of the use of sandwich panels for large-panel construction. It has been created a prototype of a two-storey house in real scale sized 3.45 X 4,2 m subjected to harmonic horizontal forces induced by a vibrodine jointed to the structure. The dynamic response of the most sensitive points has been measured by seven quartz accelerometers. These procedure has been carried out in order to obtain the principal parameters of dynamic behaviour of the prototype and to extend, after a process of dynamic identification, the numerical model to real structures. The high accelerating levels reached during the tests (10 m/s(2)) have clearly shown the capacity of resistance against dynamic actions of this building system. The reduced width (0.370 mm) of the oscillations induced during the experimental tests of the System and the level of damping underline the high capacity of energy dissipation of this buildings.

Abstract
The aim of this work is to present the results of several laboratory tests conducted by the RITAM (University of Perugia's laboratory), on Emmedue System characterized of the use of sandwich panels for large-panel construction. It has been created a prototype of a two-storey house in real scale sized 3.45 X 4,2 m subjected to harmonic horizontal forces induced by a vibrodine jointed to the structure. The dynamic response of the most sensitive points has been measured by seven quartz accelerometers. These procedure has been carried out in order to obtain the principal parameters of dynamic behaviour of the prototype and to extend, after a process of dynamic identification, the numerical model to real structures. The high accelerating levels reached during the tests (10 m/s(2)) have clearly shown the capacity of resistance against dynamic actions of this building system. The reduced width (0.370 mm) of the oscillations induced during the experimental tests of the System and the level of damping underline the high capacity of energy dissipation of this buildings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
