ABSTRACT

So, the author perform by himself and in cooperation with Z. Urbaniak, P. Flont, S. Wichniewicz, N. Jankowska, M.E. El Awadi (Egypt) some series of experiments for thin-walled structures: cantilevers under combined loading – bended eccentrically; instability effects also by loading bar by pure bimoment; transmission of torsion forces (bimoment and bendingtorsion moment) through plane nodes connecting 2 or 3 TWBs and some simple experiments for presentation for students during lectures. The attention is there focused on some examples of visible bimoment influence on instability of thin-walled bars (TWBs).
