Although plastic shear-bending buckling of the cylindrical part of FBR main vessels under horizontal earthquake loading is one of the most critical problems in structural design, the evaluation method of buckling strength is not specified in related standards in Japan. The purpose of this paper is to describe the results of static buckling tests of cylindrical shells and to present formulae for determining the allowable buckling strength of FBR main vessels. Shear buckling and bending buckling are evaluated under the assumption that both buckling modes interact slightly with each other. Shape imperfection within the plate thickness regarding shear buckling, and one-half the plate thickness regarding bending buckling is considered in the formulae originally.
