Imperfection Sensitivity of Cylindrical Shells Under Shear Loading

Abstract One of the basic load cases relevant for design shell structures is torsion, which can occur exemplary in silos and tanks under seismic actions or even wind loading. To address stability problem cylindrical shells this case, standard EN 1993‐1‐6 European Recommendation ECCS EDR5 provide simple approaches buckling shells. In order to improve current hand calculation rules given above documents, numerical study attempts include imperfection sensitivity subjected uniform torsion. present paper, theoretical, numerical, experimental results from literature are reviewed, new systematic computational analyses evaluations introduced regarding shear For purpose, a comprehensive was performed using linear nonlinear on perfect imperfect Since influence imperfections strength highly dependent pattern used models, were with three types: (i) eigenmode‐affine shape (ii) longitudinal pattern, (iii) external pressure.
