The paper relates the operations made for the seismic isolation of a tank located in Priolo Gargallo, in the Siracusa industrial area. The tank, built during the end of the seventies, is formed by a cylindrical steel shell, filled by a low temperature liquid, rested on a concrete slab, embedded on 139 columns, fitted together with the same number of foundation piles driven in the soil for about 12 meters. The friction pendulum bearing seismic devices have been adopted, installed in the superior part of the columns through the cut of a small section of the same. The intervention foresees the execution of a concrete slab at grade level, which has the functions to link all the pile heads, to furnish a rigid plan for the application to the provisional support and to anchor the new columns reinforcement bars.

Abstract
The paper relates the operations made for the seismic isolation of a tank located in Priolo Gargallo, in the Siracusa industrial area. The tank, built during the end of the seventies, is formed by a cylindrical steel shell, filled by a low temperature liquid, rested on a concrete slab, embedded on 139 columns, fitted together with the same number of foundation piles driven in the soil for about 12 meters. The friction pendulum bearing seismic devices have been adopted, installed in the superior part of the columns through the cut of a small section of the same. The intervention foresees the execution of a concrete slab at grade level, which has the functions to link all the pile heads, to furnish a rigid plan for the application to the provisional support and to anchor the new columns reinforcement bars.
