WebThe sloshing inside tank occurs when the ground motion at the site contains the period which is the same as the fundamental period of tank sloshing. The tank sloshing period depends on the size and the amount of inside fluid. For instance, the fundamental sloshing period of large tank with radius of 100m is around 10 seconds.
