Standard wave-height formula and periodic formula of various countries.

Country	Wave-height formula		Sloshing period formula
China GB50341 [14]
China GB50761 [15]
America	For functional groups I and II	For class III use function groups
API650 [16]

Note. , d is the height of the shaking wave; η is the tank type coefficient; is the long-period response spectrum adjustment coefficient; K is the spectrum acceleration adjustment coefficient, generally K = 1.5; Q is the design liquid level spectrum acceleration scaling factor, generally taking Q = 1.0; T_L is the long-term excessive period; S_o is the response spectrum response instantaneous acceleration parameter, generally S_o = 0.4S_s; S_vo is the velocity elastic spectrum value, generally taking S_vo = 1; and V₁ is the regional correction coefficient.
