Progetto esecutivo RELUIS Linea 7 - Task 7 "Metodologie di progettazione ed affidabilità di edifici protetti con sistemi di dissipazione sismica"

Ordinance 3274 (PCdM, 2003), including two chapters on the seismic isolation of buildings and bridges, represented a turning point for their practical use, removing many of the difficulties (from both the bureaucratic and technical points of view) usually encountered by the designers wishing to adopt these technologies in new or existing constructions. However, at the time when the ReLUIS Executive Project started (November 2005), there were still several problems which needed further studies, to make applications more and more reliable and easy. Some of them have been dealt with and solved by the Research Units of Project Line No. 7, who also gave their contribution toward the issuing of the relevant parts of the New Technical Regulations for Constructions (Min. Infr., 2008) and Commentary (Min. Infr., 2009), so that today many new strategic buildings in Italy are provided with seismic isolation and/or supplemental energy dissipation systems.
