Safecast Project: European Research on Seismic Behaviour of the Connections of Precast Structures

Abstract eng:
SAFECAST Project is the last of a long series of co-normative researches that supported the standardisation of precast structures within Eurocode 8. The paper presents the activity performed by the 16 European partners. The seismic behaviour of four classes of connections is investigated: floor-to-floor, floor-to-beam, beam-to-column and column-tofoundation. The experimental qualification is made in terms of strength, ductility, dissipation, deformation, decay and damage. More than 100 cyclic and dynamic tests have been performed in the laboratories of Lisbon, Milan, Ljubljana, Athens and Istanbul. But the most relevant series of tests have been performed at ELSA Laboratory of the JRC of Ispra, where a full-scale prototype of a three storeys precast structure has been subjected to pseudodynamic and cyclic tests. Other authors are presenting the details of any specific testing activity. This paper presents the design criteria deduced from these activities, as collected in the final document of design rules.
