Kurinčič, Rok (author), Hozjan, Tomaž (mentor), Bratina, Sebastjan (co-mentor)

Magistrsko delo obravnava izračun požarne odpornosti armiranobetonske okvirne konstrukcije. Vsebinsko je razdeljeno na tri dele. V prvem delu je predstavljeno teoretično ozadje izračuna požarne odpornosti armiranobetonskih konstrukcij skladno s standardom SIST EN 1992–1–2 2005. V drugem delu je predstavljena analiza in dimenzioniranje armiranobetonskih elementov s programskim orodjem Scia engineer. V tretjem delu je predstavljen račun požarne odpornosti armiranobetonske okvirne konstrukcije. Požarna odpornost je izračunana z uporabo poenostavljenih računskih metod za izpostavljenost konstrukcije standardni oziroma parametrični požarni krivulji. Za izračun časovnega razvoja temperatur v požarnem prostoru smo za primer parametrične požarne krivulje, ki predstavlja poenostavljen opis naravnega požara, uporabili program Ozone V2.2, medtem ko je časovni razvoj temperatur za standardno požarno krivuljo podan v standardu. Razvoj temperatur po prečnem prerezu smo določili s programom Heatko. V okviru analize smo prikazali vpliv izbire požarne krivulje na požarno odpornost obravnavane armiranobetonske okvirne konstrukcije.

• Title: Calculation of fire resistance of reinforced concrete portal frame construction : Master's thesis

Abstract

The thesis discusses the calculation of fire resistance of a reinforced concrete portal frame. The thesis is divided in three sections. The first part discusses the theoretical background for calculation of fire resistance of reinforced concrete construction in accordance with SIST EN 1992¬–1–2005. The second part discusses the calculation of reinforced concrete elements with the software tool Scia engineer. The third part discusses the calculation of fire resistance of reinforced concrete portal frame construction. Fire resistance is calculated using simplified calculation methods for construction exposed to standard temperature fire curve and parametric fire curve. Development of temperatures according to standard fire curve is given in standard. To calculate parametric fire curve the software tool Ozone V2.2 is used. Program calculates development of temperatures in fire sector. The development of temperatures in cross section is determined with software tool Heatko. The aim of the thesis is to calculate fire resistance of reinforced concrete portal frame construction and to show the difference between the standard temperature fire curve and parametric fire curve.
