Buckling under earthquake loading is one of the most important problems for thin-walled structures such as FBR main vessels. Therefore, Central Research Institute of Electric Power Industry (CRIEPI, Japan), commissioned by the Ministry of International Trade and Industry of the Japanese Government, has carried out the demonstration test and research program of buckling of FBR. The objectives of this paper is to describe the results of static and dynamic buckling tests and numerical analyses of cylindrical shells under horizontal loads, and to present a seismic stability assessment method for FBR main vessels. Shear-bending buckling strength evaluation formulae and response reduction factors due to nonlinearity in pre-buckling stage are worth special mention.
