ACTIVE SYSTEM OF BASE SEISMIC ISOLATION, WITH THE PROJECT OF STIFF CONNECTION WITH ALTERNATIVE FUNCTION OF THE ELASTIC ANTI-SEISMIC LINKAGE

This system based oneself essentially on the interruption of the solidariety between the building and the underlying foundation-ground complex, by ados pting multidirectional movable bearings with low coefficient of sliding or rolling friction, with or without dissipators of subsul tory seismic energy, and by applying laterally stiff connections with alternative function of elastic anti-seismic linkages.
