SEISMIC ISOLATION STRUCTURE FOR LIQUID STORAGE TANK

摘要

PROBLEM TO BE SOLVED: To provide a seismic isolation structure for liquid storage tanks which is improved in earthquake-proofness and is capable of suppressing sloshing of a liquid effectively.;SOLUTION: In a seismic isolation structure B for a tank 1 storing a liquid 6, a seismic isolation mechanism 4 is provided between the lower part of the tank 1 and the support surface 2 on which the tank is installed, and the seismic isolation structure B is provided with an inertia mass damper 8 and a synchronization type quake control mechanism 10 synchronizing with sloshing of the liquid 6 in the tank 1. The tank 1 is preferably an oil tank.;COPYRIGHT: (C)2015,JPO&INPIT
