Sloshing impact of a rectangular water tank (water tank damage caused by the kobe earthquake)

摘要

The 1995 Kobe Earthquake caused an enormous amount of damage to the Kobe area. Water tanks were heavily damaged, in particular. The tanks built in according to the old design code were broken by bulging, as shown in the 1978 Off Miyagi Earthquake. The new design code tanks, which have steel beam reinforced walls, suffered damage to their roofs as a result by sloshing. Bulging type damage was previously explained.
