Abstract

V magistrski nalogi preverjamo nosilnosti karakterističnih elementov nosilne armiranobetonske konstrukcije objekta Zdravstveni dom Ravne na Koroškem glede na stalna in začasna projektna stanja ter nezgodno (požarno) projektno stanje. Objekt je bil projektiran leta 1978 skladno s takrat veljavno zakonodajo, tako da požarna odpornost nosilne konstrukcije ni bila preverjena. Vsi računski dokazi v nalogi temeljijo na trenutno veljavnih standardih evrokod. Za izračun požarne odpornosti nosilcev in plošč je uporabljena metoda izoterme 500 °C, za izračun požarne odpornosti stebrov pa metoda B, ki upošteva tudi učinke teorije drugega reda. Za izračun časovno odvisnega temperaturnega polja v analiziranih elementih nosilne konstrukcije je uporabljen program HEATKO (Hozjan, 2009), obremenitve pa so izračunane s pomočjo idealiziranega računskega modela nosilne konstrukcije v programu SAP 2000 (Computers and Structures SAP2000 19.0.0, 2016). Kontrole nosilnosti prerezov za vsa analizirana projektna stanja so izvedena s pomočjo programa MS Excel (MS Excel 2016, 2015). Izračuni pokažejo, da vsi obravnavani nosilni elementi objekta Zdravstveni dom Ravne na Koroškem ne zadostijo kriterijem nosilnosti tako za stalna in začasna projektna stanja kot tudi za požarno projektno stanje. Nezadostno nosilnost izkazujejo predvsem medetažne plošče, medtem ko so analizirani stebri in nosilci pod ploščo ustrezni.

Secondary title: Analysis of characteristic load-bearing elements of health care building in different design situation
Secondary abstract: The master’s thesis deals with the check of the characteristic load-bearing members which are part of the reinforced concrete building “Zdravstveni dom Ravne na Koroškem” with regard to persistent and transient design situations and accidental (fire) design situation. The building was designed in 1978 in accordance with the legislation in force at the time and therefore fire resistance of the load-bearing structure was not checked. All calculations in the master thesis are based on current Eurocode standards. The 500°C isotherm method is used to calculate the fire resistance of beams and slabs, and the method B is used to calculate the fire resistance of columns, which also takes into account the effects of second order theory. To calculate the time-dependent temperature field in the load-bearing elements software HEATKO (Hozjan, 2009) is used and the internal static quantities are calculated using the software SAP 2000 (Computers and Structures SAP2000 19.0.0, 2016). All verification of the load-bearing members for all analysed design situations are performed with MS Excel (MS Excel 2016, 2015). The results show that some load-bearing members do not meet the requirements for both persistent and transient design situations and fire design situation. Particularly critical are inter-storey slabs, while the analysed columns and beams below the slab are suitable.
