Abstract: In the TOKACHIOKI Earthquake, a float roof of an oil reserve tank in TOMAKOMAI district was destroyed by sloshing, and a fire of a tank occurred as a second disaster. It is thought that the cause of sloshing outbreak was resonance a natural frequency in the long period when occurred in the TOMAKOMAI which was 200km away from seismic center and a natural frequency of oil in the tank. Oil reserve tanks around Japanese big cities are similar in the case of TOMAKOMAI district, and it is an important assignment that an earthquake resistance of a large-scale tank is improved for earthquake vibration in a long period. In this paper, we observed a sloshing characteristic looked from the experiment of a cylindrical tank model having a float roof and a method to reduce sloshing wave height by a pendulum hanged under the float roof.
