Is it possible to analyse cantilevers in LTB? If yes, which method is the calculation based on?


For the calculation of cantilevers, the determination of the ideal elastic critical moment Mcr is crucial. This can be determined for singly symmetric I-sections applying "Lohse" (LTB manual, Chapter 3.4.4). However, rotational restraints and lateral restraints are not taken into account.
