In 1985 the authors carried out a series of static tilt tests with a very big tank model in order to study the aseismic safety of large-scaled cylindrical liquid storage tanks. The model has about 10 meter diameter and 8 meter height and is made of aluminum alloy, satisfying the similitude requirements to actual large-scaled LNG, LPG and oil tanks. Prior to the static tilt tests, several cases of water-filling test of the model tank were conducted. It is very important from the point of view of tank design to grasp the tank behaviors in these conditions correctly. This paper is dealing with the water-filling behaviors of the tank which has not been clarified so far. The behaviors are discussed in relation with the initial deflections of tank shell and base plate and from comparison with the finite element analysis.
