Applying EQ forces on liquid containing tank
(OP)
How do you apply earthquake force on liquid containing steel tank such as the one shown in the attachment? Which one of the three, if any, is correct?
Thanks

You actually have to account for both the impulsive (weight of tank) and convective (weight of fluid) loads in your tank analysis.
There is a good PCA pamphlet / design guide on the subject that should help.

Granted this is written for the US codes. But, I the basic concepts and theory should allow for a relatively easy translation to the NBCC seismic forces.

For very small tanks that might not normally be designed by these methods, the design load would be a point load at the center of mass of the combined tank and fluid.
