Summary:The efficient load‐carrying behaviour of thin‐walled shells is one of the reasons for the continuing popularity of these structural elements across several fields of engineering. Locking effects limit the applicability of traditional finite element analysis (FEA) and require significant user experience in this context. Thus, shell formulations that do not show the emergence of locking effects are still a research subject. Since modelling of plates using the scaled boundary finite element method (SBFEM) showed no occurrence of locking effects the SBFEM seems to be a promising technique to avoid locking when modelling shell structures. This contribution presents the numerical analysis of thin‐walled shells using the SBFEM. Several benchmark problems for shell elements have been investigated and the results for the Scordelis‐Lo roof are presented in detail.
