Design fire load of the roof and facade steel structure - Reconstruction of the Sava Centre

Abstract

Reconstruction of the Sava Centre in Belgrade, a cultural good of the Republic of Serbia, includes works on the facility, ensuring that the congress centre's construction meets all modern requirements for fire protection. The paper presents the design fires used to conduct fire resistance design of the steel structure of the roof and facade. By applying analytical procedures defined in Eurocodes for structures and performing advanced CFD analysis, it has been shown that most of the purlins in Building A of the Sava Centre satisfy the required 60 minutes of fire resistance. This paper also presents the calculation of the fire loads applied in design fires.

Rekonstrukcija Sava Centra u Beogradu, kulturnog dobra Republike Srbije, podrazumeva radove na objektu, koji moraju da obezbede da konstrukcija kongresnog centra ispunjava sve savremene zahteve protivpožarne zaštite. U radu su prikazni proračunski požari korišćeni za dokaz otpornosti na dejstvo požara čelične konstrukcije krova i fasade. Primenom analitičkih postupaka definisanih u Evrokodovima za konstrukcije i napredne CFD analize pokazano je da veći deo rožnjača u bloka A Sava Centra zadovoljava nosivost pri dejstvu požara u trajanju od 60 minuta. Sračunavanje požarnih opterećenja pri definisanju proračunskih požara takođe je prikazano u ovom radu.
