| Abstract: |
Numerical buckling strength verification of cylindrical steel shells subjected to circumferential compression - A new approach.In the paper it is shown that eigenmode-affine imperfection patterns are problematic for a numerical buckling analysis according to Eurocode for cylindrical steel shells subjected to circumferential compression. In contrast, natural longitudinal imperfections derived from the concept of quasi-collapse-affine imperfections are suited to accomplish a consistent transition from the classical to the new numerical buckling strength verification technique through the determination of consistent imperfection amplitudes. |
