Języki publikacji
Abstrakty
Wyboczenie sprężyste ogólne, postaciowe i miejscowe belek cienkościennych o przekrojach otwartych jest opisane z uwzględnieniem aktualnych osiągnięć w świecie. Wyróżnione trzy rodzaje wyboczeń przedstawiono dla przykładowych belek. Zamieszczono rozwiązania analityczne i numeryczne metodą pasm skończonych (FSM). Wskazano na założenia teorii Vlasova dla prętów cienkościennych i zakres jej stosowania. Zwrócono uwagę na wyboczenie postaciowe pręta, które może mieć istotne znaczenie w projektowaniu konstrukcji.
The elastic general, shaped and local thin-walled beams with open cross-section is described with taking into account the current developments in the world. The distinguished three types of bucklings are presented for the exemplary beams. The analytical and numerical solutions with the finite bands methods (FSM) are placed. It is pointed to the assumptions of Vlasova theory for thin-walled rods and its scope. It is paid attention to the shaped buckling of rod which may be important in designing of the construction.
