The subject of this paper is to investigate the sloshing behavior of floating-roofed oil storage tanks through theoretical analysis and model testing. The analysis employed theory of fluid-elastic vibration to study the interaction between a roof and the contained liquid. The finite element method was applied, in which a technique based on the variational principle of boundary integrals was used to simplify the solution. The theory was verified by shake table experiments with three large models of single deck type and double deck type of floating roofs. From these results we have come to the following conclusions:
1. The existence of floating roofs hardly affects the first natural mode of sloshing.
2. The influence of the higher modes should be considered in determining stresses of double deck type floating roofs.
3. The local deformation of the lower deck plays a great role on the sloshing behavior.
