Within the SAFECAST Research project, a large experimental campaign on the real time behaviour of a full scale multi-storey precast frame mounted in the Elsa/JRC laboratory can give straightforward suggestions for a relaunch of the precast concrete industry in the realization of multi-storey prefabricated structures. The 3-storey dry assembled structure, without cast-in-situ slab, with dowel and mutual weld connections to realize a rigid diaphragm, the flat slab at the intrados, the stable straight floor members without camber, the adaptation of hinged nodes to clamped, the reduction of the nodal moments with respect to the cast-in-situ technology, the freedom to choose wherever and whenever to adapt the nodes to clamped, displays important subjects that confirm the great advantages of prefabrication especially in seismic area with respect to the traditional cast-in-situ structures.

Abstract
Within the SAFECAST Research project, a large experimental campaign on the real time behaviour of a full scale multi-storey precast frame mounted in the Elsa/JRC laboratory can give straightforward suggestions for a relaunch of the precast concrete industry in the realization of multi-storey prefabricated structures. The 3-storey dry assembled structure, without cast-in-situ slab, with dowel and mutual weld connections to realize a rigid diaphragm, the flat slab at the intrados, the stable straight floor members without camber, the adaptation of hinged nodes to clamped, the reduction of the nodal moments with respect to the cast-in-situ technology, the freedom to choose wherever and whenever to adapt the nodes to clamped, displays important subjects that confirm the great advantages of prefabrication especially in seismic area with respect to the traditional cast-in-situ structures.
