Fluid forces reacting on structures should be taken into consideration in response analyses of structures contained fluid. We investigated added mass to evaluate seismic loads of water contained in a toroidal tank. The water height was about 40% of the total height of the tank. We calculated the added mass by commercial structural analysis software and it was 20% of total mass of water. For comparison, we obtained the loads from commercial fluid analysis software and the shaking table test of 1/20 scale tank. The calculated added mass agreed well with the equivalent mass obtained from the fluid analysis software and the shaking table test.
