Popis: U važećem evropskom standardu SRPS EN 1993-1-4 nisu eksplicitno definisana pravila za proračun centrično pritisnutih elemenata ravnokrakog L poprečnog preseka od nerđajućeg čelika. Ovaj rad ukratko prikazuje rezultate opsežnog istraživanja sprovedenog na ovom tipu konstruktivnih elemenata sa ciljem definisanja preporuka za njihov proračun. Istraživanje je sprovedeno na Univerzitetu u Beogradu na Građevinskom fakultetu i publikovano u doktorskoj disertaciji „Nosivost različitih tipova ravnokrakih ugaonika od nerđajućeg čelika pri dejstvu centričnog pritiska“. Analizirana su tri tipa čeličnih proizvoda, vrućevaljane, laserski zavarene i hladnooblikovane elemente i dve legure nerđajućeg čelika, austenitna i niskolegirana dupleks legura. Na osnovu sistematičnog eksperimentalnog istraživanja i detaljne numeričke analize preporučene su krive izvijanja za kontrolu stabilnosti na fleksiono i fleksiono-torziono izvijanje u skladu sa evropskim proračunskim procedurama. The current European standard SRPS EN 1993-1-4 does not explicitly define the rules for the the design of stainless steel axially compressed equal angle columns. This paper briefly presents the results of extensive research conducted on this type of structural elements with the aim of defining recommendations for their design. The research was carried out at University of Belgrade, Faculty of Civil Engineering and published in PhD thesis "Resistance of different types of stainless steel equal angles under axial compression". Three types of steel products (hot-rolled, laser-welded and cold-formed) and two stainless steel alloys (austenitic and low alloy duplex steel) were analysed. Based on systematic experimental research and detailed numerical analysis, buckling curves were recommended for stability control in flexural and flexural-torsional buckling in accordance with European design procedures.
