In order to investigate the uplifting behavior of large-scaled LNG, LPG and oil tanks, which has recently been said to be closely related with the earthquake damages, the authors conducted a series of static tilt tests using a very big model made of aluminum alloy with about 10m diameter and 8m height. This model is characteristic of satisfying almost perfectly the similitude to actual large-scaled tanks, and the tilt test made it possible to conduct such big experiments and to measure in detailes the behaviors.In the experiment, many anchored cases were carried out, the parameters of which are rigidity of anchor strap, magnitude of anchor prestress and so on. The subjects of this paper are to introduce the outline of the static tilt tests and to discuss about the influence of anchor rigidity.
