ABSTRACT:
A method of protecting liquid storage tanks from earthquakes and an anchor especially adapted to carry out this method are described. The method includes providing an energy dissipating anchor between the liquid tank and structure which will move with the ground. The anchor includes a stainless steel shaft which is secured to a ring foundation. This shaft is surrounded by a clamp which frictionally grips the same and is secured to the tank.
