Abstract

Čelični elementi koji su istovremeno izloženi tlaku i savijanju, zahtijevaju posebnu pažnju prilikom proračuna konstrukcije. Za navedenu interakciju, Eurocode nudi dvije varijante proračuna, Metodu 1 i Metodu 2. Budući da su metode utemeljene na različitim pretpostavkama, samim time imaju i drugačiju primjenu te razliku u krajnjem rezultatu. Teorijski dio ovog rada daje pregled proračuna konstrukcija na razini poprečnog presjeka i na razini elementa te općenit osvrt na dokaze pouzdanosti prema Eurocode-u. U praktičnom dijelu rada, dana je usporedba dva različita profila (HEA i IPE), različitih klasa ( 1 i 3) opterećenih dvoosnim savijanjem, koncentriranim ili kontinuiranim opterećenjem i tlačnom silom, s ciljem usporedbe ranije spomenutih dviju metoda.

Abstract (english)

Steel members which are simultaneously exposed to axial compression and bending, require special attention while designing the structure. For this specific interaction, Eurocode offers two procedures, Method 1 and Method 2. Since the methods are based on different assumptions, they have a different application and a difference in the end result. The theoretical part of this paper provides an overview of the design of structures, both cross-sections and members. It also gives a general overview of the evidence of reliability according to Eurocode. The practical part of the paper shows a comparison of two different beam profiles (IPE and HEA)and different classes ( 1 and 3) loaded with biaxial bending, concentrated or continuous, and axial compression, with the aim of comparing the two methods previously mentioned.
