A seismic isolation and fuzzy vibration control system, which is comprised of a shell with springs and variable dampers between the shell and the ground, is proposed. When the shell shakes due to vertical seismic forces, the seismic isolation system is implemented and fuzzy vibration control is carried out. The damping ratios are adjusted by fuzzy theory, and stresses in the shell are reduced. The validity of seismic isolation and the fuzzy control system of the shell subjected to seismic forces is proven.
