Upper-bound estimation of the load-capacity of cold-formed steel sections (TWCFS) with perforations, subjected to axial compression is presented. The estimation is performed on the basis of the Yield Line Analysis ((YLA). TWCFS lipped channel sections with two sets of perforations (on the web and on the flanges) are under investigation. The comparison of experimental results, FE simulation results, European code ultimate strength predictions and upper-bound estimation based on YLA approach is carried out and presented. Some conclusions concerning an applicability of the YLA approach for ultimate strength prediction of perforated TWCFS structural members are derived.

W artykule przedstawiono wyniki górnego oszacowania nośności cienkościennych prętów zimno formowanych z perforacjami, poddanych osiowemu ściskaniu. Oszacowanie to jest oparte na metodzie załomów plastycznych. Rozpatrywano dwa warianty perforacji (środnika i pasów) cienkościennych prętów ceowych z żebrami końcowymi. Przeprowadzono analizę porównawczą wyników eksperymentu, wyników symulacji numerycznych MES oraz wyników obliczeń wg wzorów normatywnych normy europejskiej z wynikami oszacowania górnego nośności opartego na metodzie załomów plastycznych. Sformułowano wnioski dotyczące możliwości zastosowania tej metody do szacowania nośności cienkościennych prętów zimno formowanych z perforacjami.
