Abstract

Diplomski rad obuhvaća analizu spregnute konstrukcije višekatne zgrade izložene požarnom djelovanju. Tlocrtne dimenzije konstrukcije su 21,0 m x 32,0 m. Visina konstrukcije je 14,4 m, dok je visina svake etaže 3,6 m. U radu je provedena analiza opterećenja i dimenzioniranje elemenata na dobiveno mjerodavno opterećenje. 3D model konstrukcije je izrađen u programskom paketu SCIA Engineer 21.1, uz pomoć kojeg je proveden proračun unutarnjih sila statičkom analizom II. reda. Provedena je i seizmička analiza koja je rezultirala manjim unutarnjim silama i momentima u usporedbi sa statičkom analizom. Proračun elemenata konstrukcije na djelovanje požara proveden je pojednostavljenim postupkom primjenom nominalnog požara. Požarna otpornost nezaštićenih i zaštićenih elemenata u zahtijevanom vremenu dobivena je proračunom na požar prema EN 1993-1-2 i napravljena je usporedba sa rezultatima dobivenima iz programskog paketa za požar OZone 3.0.4. U radu je provedeno i dimenzioniranje priključaka elemenata konstrukcije.

Abstract (english)

The master thesis includes the analysis of a steel concrete composite structure of multi-story building exposed to fire. The floor plan dimensions of the structure are 21,0 m x 32,0 m. The height of the structure is 14,4 m, while the height of each floor is 3.6 m. Thesis includes relevant loads analysis and design of elements to load effects. The 3D model of the structure was created in the SCIA Engineer 21.1 software package, with the help of which internal forces were calculated by static analysis II. order. A seismic analysis was also carried out, which gave less internal forces and bending moments compared to the static analysis. The design of structural elements for fire action was carried out by a simplified procedure using a nominal fire. The fire resistance of unprotected and protected elements in the required time was obtained by fire calculation according to EN 1993-1-2 and a comparison was made with the results obtained from the software OZone 3.0.4. The thesis also consists of structural elements joints design.
