In the paper, experimental and numerical investigations of thin-walled beams with doublebox flanges were presented. They were a continuation of researches conducted at the Unit of Strength of Materials and Structures at Poznan University of Technology. Numerical results obtained with the Finite Strip Method (FSM) were compared with experimental ones and used for validation of analytical solutions.

W pracy przedstawiono badania doświadczalne i numeryczne belek cienkościennych z półkami skrzynkowymi. Zagadnienie to jest kontynuacją badań przeprowadzonych w Zakładzie Wytrzymałości Materiałów i Konstrukcji Politechniki Poznańskiej. Wyniki numeryczne otrzymane z wykorzystaniem metody pasm skończonych porównano z wynikami uzyskanymi z eksperymentu, a następnie użyto do weryfikacji rozwiązań analitycznych.
