FIELD: construction, applicable for enhancing the seismic stability and durability of structure. SUBSTANCE: a reinforced-concrete toroid-shaped closed section shell with a diameter equal to 0.8-1.0 of the tank height is made around the edges of the cylindrical tank, the gap between the toroid-shaped shell and tank is filled with sand or clay-sand mix with a clay-to-sand ratio equal to 1:10-1:15, then a compacted earth embankment is erected around the outer edges of the toroid- shaped shell. EFFECT: enhanced seismic stability and durability of the structure. 1 dwg
