Buckling tests for nearly perfect cylinders and cylinders with intentional imperfection made by press-working technique were carried out under transverse shearing loads. The radius-to-thickness ratios were 50-200 and bending-to-shear stress ratios were 1.2-5.0, where both types of elastic-plastic buckling in shear and in bending occurred. The purpose of these tests was to clarify the effects of imperfection on these two types of buckling. From test results and numerical analyses, some margin was recognized in the design formulae even for imperfect cylinders whose imperfection amplitudes were within the wall thickness (in shear) and one-half the value of the wall thickness (in bending). We proposed the correction factors of buckling load for larger imperfections in the seismic buckling design guideline of FBR
