Abstract

U uvodnom dijelu rada prikazano je ponašanje drvenih konstrukcija u požaru kroz opis metoda požarnog proračuna konstrukcija. Nadalje, u drugom dijelu rada napravljen je vizualni pregled dijela krovišta Stare gradske vijećnice u Zagrebu, Ćirilometodska ul. 5, 10000, Zagreb, zona 5. Nakon vizualnog pregleda konstrukcije provedena je ocjena mehaničkih karakteristika elemenata krovišta nerazornim ispitivanjima pomoću vlagomjera i rezistografa. Na temelju prikupljenih mehaničkih i geometrijskih karakteristika krovišta te sagledavanja statičkog sustava krovišta, pristupilo se izradi statičkog modela krovišta u programu Dlubal RFEM 6 i izradi proračuna nosive konstrukcije. Proračun se sastoji od provjere graničnih stanja nosivosti i uporabljivosti prema Eurokodu 5: Projektiranje drvenih konstrukcija te prema hrvatskim nacionalnim dodacima za projektiranje drvenih konstrukcija.

Abstract (english)

In the introductory part of the paper, the behavior of wooden structures in a fire is presented through a description of the methods of fire calculation of structures. Furthermore, in the second part of the work a visual inspection of part of the roof Old Town Hall in Zagreb, Ćirilometodska St, 5, 10000, Zagreb, zone 5 was made. After a visual inspection of the structure, an evaluation of the mechanical characteristics of the roofing elements was carried out by non-destructive testing using a hygrometer and a resistograph. Based on the collected mechanical and geometrical characteristics of the roof and analyzing the static system of the roof, the creation of a static model of the roof in the Dlublal RFEM 6 program was made, as well as a static calculation of it. The calculation consists of checking the limit states of load capacity and serviceability according to Eurocode 5: Design of wooden structures and according to the Croatian national annexes for designing of the wooden structures.
