Abstract

Suvremeni pristup projektiranja čeličnih konstrukcija omogućuje izradu ekonomičnijih i pouzdanih konstrukcija. Najvažniji pristup takvom načinu projektiranja je koncept djelomično nepopustljivih priključaka. U ovome radu predstavljen je koncept utjecaja krutosti priključaka na ponašanje konstrukcije - čeličnog okvira. Navedeni koncept s jedne strane zahtijeva nešto više znanja i vremena kod projektiranja, ali s druge strane omogućuje znatne uštede u materijalu i radu potrebnom za izradu najčešćih čeličnih konstrukcija - okvira (Skejić & Jamaković, 2012). Bit rada je što realnija analiza ponašanja priključka i njihovog utjecaja na globalno ponašanje konstrukcije. Provedena je usporedba ponašanja konstrukcije s konzervativnim nepopustljivim, optimalnim nepopustljivim i djelomično nepopustljivim priključcima na konkretnoj konstrukciji dvobrodne dvoetažne zgrade. Postignuta je ušteda na materijalu, ali najviše se uštedjelo na ljudskom radu što je bio i primarni cilj. Da bi projektant ostao konkurentan morati će usvojiti suvremene pristupe i vještine koje daje Europska norma. Uz navedeno, prikazan je proračun priključaka novom CBFEM metodom koja omogućuje još realniju procjenu njihovog ponašanja.

Abstract (english)

The modern approach in design of steel structures enables production of more economical and reliable structures. The most important approach to this is the concept of semi-rigid joints. This work presents how stiffness of a joints influence on the behaviour of a structure - steel frame. This concept on the one hand requires a bit more knowledge and time spent in design, but on the other hand allows significant savings in material and labour (Skejić & Jamaković, 2012). The essence of this work is to perform analysis of real joints stiffness and to see their impact on the global behaviour of a structure. A comparison between structure behaviour with conservative rigid, optimal rigid and semi-rigid joints on 2-bay 2-storey building was performed. Material savings were achieved, but most of the savings were on human labour, which was also the primary goal. To remain competitive, designer should adopt modern approaches and skills provided by the European standard. In addition, the calculation of joints with the new CBFEM method, which enables an even more realistic assessment of their behaviour, is presented.
